YUM.CONF(5)                        DNF                       YUM.CONF(5)

NAME         top

       yum.conf - redirecting to DNF Configuration Reference

DESCRIPTION         top

       DNF by default uses the global configuration file at
       /etc/dnf/dnf.conf and all *.repo files found under
       /etc/yum.repos.d. The latter is typically used for repository
       configuration and takes precedence over global configuration.

       The configuration file has INI format consisting of section
       declaration and name=value options below each on separate line.
       There are two types of sections in the configuration files: main
       and repository. Main section defines all global configuration
       options and should be only one.

       The repository sections define the configuration for each (remote
       or local) repository. The section name of the repository in
       brackets serve as repo ID reference and should be unique across
       configuration files. The allowed characters of repo ID string are
       lower and upper case alphabetic letters, digits, -, _, .  and :.
       The minimal repository configuration file should aside from repo
       ID consists of baseurl, metalink or mirrorlist option definition.

DISTRIBUTION-SPECIFIC CONFIGURATION         top

       Configuration options, namely best and skip_if_unavailable, can
       be set in the DNF configuration file by your distribution to
       override the DNF defaults.

[MAIN] OPTIONS         top

       allow_vendor_change
              boolean

              If disabled dnf will stick to vendor when upgrading or
              downgrading rpms.  Default is True

              WARNING:
                 This option is currently not supported for downgrade
                 and distro-sync commands

       arch   string

              The architecture used for installing packages. By default
              this is auto-detected. Often used together with ignorearch
              option.

       assumeno
              boolean

              If enabled dnf will assume No where it would normally
              prompt for confirmation from user input. Default is False.

       assumeyes
              boolean

              If enabled dnf will assume Yes where it would normally
              prompt for confirmation from user input (see also
              defaultyes). Default is False.

       autocheck_running_kernel
              boolean

              Automatic check whether there is installed newer kernel
              module with security update than currently running kernel.
              Default is True.

       basearch
              string

              The base architecture used for installing packages. By
              default this is auto-detected.

       best   boolean

              True instructs the solver to either use a package with the
              highest available version or fail. On False, do not fail
              if the latest version cannot be installed and go with the
              lower version. The default is False.  Note this option in
              particular can be set in your configuration file by your
              distribution. Also note that the use of the highest
              available version is only guaranteed for the packages
              directly requested and not for their dependencies.

       cachedir
              string

              Path to a directory used by various DNF subsystems for
              storing cache data.  Has a reasonable root-writable
              default depending on the distribution. DNF needs to be
              able to create files and directories at this location.

       cacheonly
              boolean

              If set to True DNF will run entirely from system cache,
              will not update the cache and will use it even in case it
              is expired. Default is False.

       check_config_file_age
              boolean

              Specifies whether dnf should automatically expire metadata
              of repos, which are older than their corresponding
              configuration file (usually the dnf.conf file and the
              foo.repo file).  Default is True (perform the check).
              Expire of metadata is also affected by metadata age.  See
              also metadata_expire.

       clean_requirements_on_remove
              boolean

              Remove dependencies that are no longer used during dnf
              remove. A package only qualifies for removal via
              clean_requirements_on_remove if it was installed through
              DNF but not on explicit user request, i.e. it was pulled
              in as a dependency. The default is True.  (installonlypkgs
              are never automatically removed.)

       config_file_path
              string

              Path to the default main configuration file. Default is
              /etc/dnf/dnf.conf.

       debuglevel
              integer

              Debug messages output level, in the range 0 to 10. The
              higher the number the more debug output is put to stdout.
              Default is 2.

       debug_solver
              boolean

              Controls whether the libsolv debug files should be created
              when solving the transaction. The debug files are created
              in the ./debugdata directory.  Default is False.

       defaultyes
              boolean

              If enabled the default answer to user confirmation prompts
              will be Yes. Not to be confused with assumeyes which will
              not prompt at all. Default is False.

       diskspacecheck
              boolean

              Controls wheather rpm shoud check available disk space
              during the transaction.  Default is True.

       errorlevel
              integer

              Error messages output level, in the range 0 to 10. The
              higher the number the more error output is put to stderr.
              Default is 3. This is deprecated in DNF and overwritten by
              --verbose commandline option.

       exit_on_lock
              boolean

              Should the dnf client exit immediately when something else
              has the lock. Default is False.

       gpgkey_dns_verification
              boolean

              Should the dnf attempt to automatically verify GPG
              verification keys using the DNS system. This option
              requires the unbound python module (python3-unbound) to be
              installed on the client system. This system has two main
              features. The first one is to check if any of the already
              installed keys have been revoked. Automatic removal of the
              key is not yet available, so it is up to the user, to
              remove revoked keys from the system. The second feature is
              automatic verification of new keys when a repository is
              added to the system. In interactive mode, the result is
              written to the output as a suggestion to the user. In
              non-interactive mode (i.e. when -y is used), this system
              will automatically accept keys that are available in the
              DNS and are correctly signed using DNSSEC. It will also
              accept keys that do not exist in the DNS system and their
              NON-existence is cryptographically proven using DNSSEC.
              This is mainly to preserve backward compatibility.
              Default is False.

       group_package_types
              list

              List of the following: optional, default, mandatory. Tells
              dnf which type of packages in groups will be installed
              when ‘groupinstall’ is called. Default is: default,
              mandatory.

       ignorearch
              boolean

              If set to True, RPM will allow attempts to install
              packages incompatible with the CPU’s architecture.
              Defaults to False. Often used together with arch option.

       installonlypkgs
              list

              List of provide names of packages that should only ever be
              installed, never upgraded. Kernels in particular fall into
              this category.  These packages are never removed by dnf
              autoremove even if they were installed as dependencies
              (see clean_requirements_on_remove for auto removal
              details).  This option append the list values to the
              default installonlypkgs list used by DNF. The number of
              kept package versions is regulated by installonly_limit.

       installonly_limit
              integer

              Number of installonly packages allowed to be installed
              concurrently. Defaults to 3. The minimal number of
              installonly packages is 2. Value 0 means unlimited number
              of installonly packages. Value 1 is explicitely not
              allowed since it complicates kernel upgrades due to
              protection of the running kernel from removal.

       installroot
              string

              The root of the filesystem for all packaging operations.
              It requires an absolute path. See also –installroot
              commandline option.

       install_weak_deps
              boolean

              When this option is set to True and a new package is about
              to be installed, all packages linked by weak dependency
              relation (Recommends or Supplements flags) with this
              package will be pulled into the transaction.  Default is
              True.

       keepcache
              boolean

              Keeps downloaded packages in the cache when set to True.
              Even if it is set to False and packages have not been
              installed they will still persist until next successful
              transaction. The default is False.

       logdir string

              Directory where the log files will be stored. Default is
              /var/log.

       logfilelevel
              integer

              Log file messages output level, in the range 0 to 10. The
              higher the number the more debug output is put to logs.
              Default is 9.

              This option controls dnf.log, dnf.librepo.log and
              hawkey.log. Although dnf.librepo.log and hawkey.log are
              affected only by setting the logfilelevel to 10.

       log_compress
              boolean

              When set to True, log files are compressed when they are
              rotated. Default is False.

       log_rotate
              integer

              Log files are rotated log_rotate times before being
              removed. If log_rotate is 0, the rotation is not
              performed.  Default is 4.

       log_size
              storage size

              Log  files are rotated when they grow bigger than log_size
              bytes. If log_size is 0, the rotation is not performed.
              The default is 1 MB. Valid units are ‘k’, ‘M’, ‘G’.

              The size applies for individual log files, not the sum of
              all log files.  See also log_rotate.

       metadata_timer_sync
              time in seconds

              The minimal period between two consecutive makecache timer
              runs. The command will stop immediately if it’s less than
              this time period since its last run. Does not affect
              simple makecache run. Use 0 to completely disable
              automatic metadata synchronizing. The default corresponds
              to three hours. The value is rounded to the next commenced
              hour.

       module_obsoletes
              boolean

              This option controls whether dnf should apply modular
              obsoletes when possible.

       module_platform_id
              string

              Set this to $name:$stream to override PLATFORM_ID detected
              from /etc/os-release.  It is necessary to perform a system
              upgrade and switch to a new platform.

       module_stream_switch
              boolean

              This option controls whether it’s possible to switch
              enabled streams of a module.

       multilib_policy
              string

              Controls how multilib packages are treated during install
              operations. Can either be "best" (the default) for the
              depsolver to prefer packages which best match the system’s
              architecture, or "all" to install all available packages
              with compatible architectures.

       obsoletes
              boolean

              This option only has affect during an install/update. It
              enables dnf’s obsoletes processing logic, which means it
              makes dnf check whether any dependencies of given package
              are no longer required and removes them.  Useful when
              doing distribution level upgrades.  Default is ‘true’.

              Command-line option: –obsoletes

       persistdir
              string

              Directory where DNF stores its persistent data between
              runs. Default is "/var/lib/dnf".

       pluginconfpath
              list

              List of directories that are searched for plugin
              configurations to load. All configuration files found in
              these directories, that are named same as a plugin, are
              parsed. The default path is /etc/dnf/plugins.

       pluginpath
              list

              List of directories that are searched for plugins to load.
              Plugins found in any of the directories in this
              configuration option are used. The default contains a
              Python version-specific path.

       plugins
              boolean

              Controls whether the plugins are enabled. Default is True.

       protected_packages
              list

              List of packages that DNF should never completely remove.
              They are protected via Obsoletes as well as user/plugin
              removals.

              The default is: dnf, glob:/etc/yum/protected.d/*.conf and
              glob:/etc/dnf/protected.d/*.conf. So any packages which
              should be protected can do so by including a file in
              /etc/dnf/protected.d with their package name in it.

              DNF will protect also the package corresponding to the
              running version of the kernel. See also
              protect_running_kernel option.

       protect_running_kernel
              boolean

              Controls whether the package corresponding to the running
              version of kernel is protected from removal. Default is
              True.

       releasever
              string

              Used for substitution of $releasever in the repository
              configuration.  See also repo variables.

       reposdir
              list

              DNF searches for repository configuration files in the
              paths specified by reposdir. The behavior of reposdir
              could differ when it is used along with --installroot
              option.

       rpmverbosity
              string

              RPM debug scriptlet output level. One of: critical,
              emergency, error, warn, info or debug. Default is info.

       strict boolean

              If disabled, all unavailable packages or packages with
              broken dependencies given to DNF command will be skipped
              without raising the error causing the whole operation to
              fail. Currently works for install command only. The
              default is True.

       tsflags
              list

              List of strings adding extra flags for the RPM
              transaction.

                     ┌─────────────┬────────────────────────────┐
                     │tsflag value │ RPM Transaction Flag       │

                     └─────────────┴────────────────────────────┘

              The nocrypto option will also set the _RPMVSF_NOSIGNATURES
              and _RPMVSF_NODIGESTS VS flags. The test option provides a
              transaction check without performing the transaction. It
              includes downloading of packages, gpg keys check
              (including permanent import of additional keys if
              necessary), and rpm check to prevent file conflicts.  The
              nocaps is supported with rpm-4.14 or later. When nocaps is
              used but rpm doesn’t support it, DNF only reports it as an
              invalid tsflag.

       upgrade_group_objects_upgrade
              boolean

              Set this to False to disable the automatic running of
              group upgrade when running the upgrade command. Default is
              True (perform the operation).

       varsdir
              list

              List of directories where variables definition files are
              looked for. Defaults to "/etc/dnf/vars", "/etc/yum/vars".
              See variable files in Configuration reference.

       zchunk boolean

              Enables or disables the use of repository metadata
              compressed using the zchunk format (if available). Default
              is True.

[MAIN] OPTIONS - COLORS         top

       color  string

              Controls if DNF uses colored output on the command line.
              Possible values: “auto”, “never”, “always”. Default is
              “auto”.

REPO OPTIONS         top

       baseurl
              list

              List of URLs for the repository. Defaults to [].

       cost   integer

              The relative cost of accessing this repository, defaulting
              to 1000. This value is compared when the priorities of two
              repositories are the same. The repository with the lowest
              cost is picked. It is useful to make the library prefer
              on-disk repositories to remote ones.

       enabled
              boolean

              Include this repository as a package source. The default
              is True.

       gpgkey list of strings

              URLs of a GPG key files that can be used for signing
              metadata and packages of this repository, empty by
              default. If a file can not be verified using the already
              imported keys, import of keys from this option is
              attempted and the keys are then used for verification.

       metalink
              string

              URL of a metalink for the repository. Defaults to None.

       mirrorlist
              string

              URL of a mirrorlist for the repository. Defaults to None.

       module_hotfixes
              boolean

              Set this to True to disable module RPM filtering and make
              all RPMs from the repository available. The default is
              False.  This allows user to create a repository with
              cherry-picked hotfixes that are included in a package set
              on a modular system.

       name   string

              A human-readable name of the repository. Defaults to the
              ID of the repository.

       priority
              integer

              The priority value of this repository, default is 99. If
              there is more than one candidate package for a particular
              operation, the one from a repo with the lowest priority
              value is picked, possibly despite being less convenient
              otherwise (e.g. by being a lower version).

       type   string

              Type of repository metadata. Supported values are: rpm-md.
              Aliases for rpm-md: rpm, repomd, rpmmd, yum, YUM.

REPO VARIABLES         top

       Right side of every repo option can be enriched by the following
       variables:

       $arch
          Refers to the system’s CPU architecture e.g, aarch64, i586,
          i686 and x86_64.

       $basearch
          Refers to the base architecture of the system. For example,
          i686 and i586 machines both have a base architecture of i386,
          and AMD64 and Intel64 machines have a base architecture of
          x86_64.

       $releasever
          Refers to the release version of operating system which DNF
          derives from information available in RPMDB.

       In addition to these hard coded variables, user-defined ones can
       also be used. They can be defined either via variable files, or
       by using special environmental variables. The names of these
       variables must be prefixed with DNF_VAR_ and they can only
       consist of alphanumeric characters and underscores:

          $ DNF_VAR_MY_VARIABLE=value

       To use such variable in your repository configuration remove the
       prefix. E.g.:

          [myrepo]
          baseurl=https://example.site/pub/fedora/$MY_VARIABLE/releases/$releasever

       Note that it is not possible to override the arch and basearch
       variables using either variable files or environmental variables.

       Although users are encouraged to use named variables, the
       numbered environmental variables DNF0 - DNF9 are still supported:

          $ DNF1=value

          [myrepo]
          baseurl=https://example.site/pub/fedora/$DNF1/releases/$releasever

OPTIONS FOR BOTH [MAIN] AND REPO         top

       Some options can be applied in either the main section, per
       repository, or in a combination. The value provided in the main
       section is used for all repositories as the default value, which
       repositories can then override in their configuration.

       bandwidth
              storage size

              Total bandwidth available for downloading. Meaningful when
              used with the throttle option. Storage size is in bytes by
              default but can be specified with a unit of storage. Valid
              units are ‘k’, ‘M’, ‘G’.

       countme
              boolean

              Determines whether a special flag should be added to a
              single, randomly chosen metalink/mirrorlist query each
              week.  This allows the repository owner to estimate the
              number of systems consuming it, by counting such queries
              over a week’s time, which is much more accurate than just
              counting unique IP addresses (which is subject to both
              overcounting and undercounting due to short DHCP leases
              and NAT, respectively).

              The flag is a simple “countme=N” parameter appended to the
              metalink and mirrorlist URL, where N is an integer
              representing the “longevity” bucket this system belongs
              to.  The following 4 buckets are defined, based on how
              many full weeks have passed since the beginning of the
              week when this system was installed: 1 = first week, 2 =
              first month (2-4 weeks), 3 = six months (5-24 weeks) and 4
              = more than six months (> 24 weeks).  This information is
              meant to help distinguish short-lived installs from
              long-term ones, and to gather other statistics about
              system lifecycle.

              Default is False.

       deltarpm
              boolean

              When enabled, DNF will save bandwidth by downloading much
              smaller delta RPM files, rebuilding them to RPM locally.
              However, this is quite CPU and I/O intensive. Default is
              True.

       deltarpm_percentage
              integer

              When the relative size of delta vs pkg is larger than
              this, delta is not used.  Default value is 75 (Deltas must
              be at least 25% smaller than the pkg).  Use 0 to turn off
              delta rpm processing. Local repositories (with file://
              baseurl) have delta rpms turned off by default.

       enablegroups
              boolean

              Determines whether DNF will allow the use of package
              groups for this repository. Default is True (package
              groups are allowed).

       excludepkgs
              list

              Exclude packages of this repository, specified by a name
              or a glob and separated by a comma, from all operations.
              Can be disabled using --disableexcludes command line
              switch.  Defaults to [].

       fastestmirror
              boolean

              If enabled a metric is used to find the fastest available
              mirror. This overrides the order provided by the
              mirrorlist/metalink file itself. This file is often
              dynamically generated by the server to provide the best
              download speeds and enabling fastestmirror overrides this.
              The default is False.

       gpgcheck
              boolean

              Whether to perform GPG signature check on packages found
              in this repository.  The default is False.

              This option can only be used to strengthen the active RPM
              security policy set with the %_pkgverify_level macro (see
              the /usr/lib/rpm/macros file for details).  That means, if
              the macro is set to ‘signature’ or ‘all’ and this option
              is False, it will be overridden to True during DNF
              runtime, and a warning will be printed.  To squelch the
              warning, make sure this option is True for every enabled
              repository, and also enable localpkg_gpgcheck.

       includepkgs
              list

              Include packages of this repository, specified by a name
              or a glob and separated by a comma, in all operations.
              Inverse of excludepkgs, DNF will exclude any package in
              the repository that doesn’t match this list. This works in
              conjunction with excludepkgs and doesn’t override it, so
              if you ‘excludepkgs=*.i386’ and ‘includepkgs=python*’ then
              only packages starting with python that do not have an
              i386 arch will be seen by DNF in this repo.  Can be
              disabled using --disableexcludes command line switch.
              Defaults to [].

       ip_resolve
              IP address type

              Determines how DNF resolves host names. Set this to
              ‘4’/’IPv4’ or ‘6’/’IPv6’ to resolve to IPv4 or IPv6
              addresses only. By default, DNF resolves to either
              addresses.

       localpkg_gpgcheck
              boolean

              Whether to perform a GPG signature check on local packages
              (packages in a file, not in a repository).  The default is
              False.  This option is subject to the active RPM security
              policy (see gpgcheck for more details).

       max_parallel_downloads
              integer

              Maximum number of simultaneous package downloads. Defaults
              to 3. Maximum of 20.

       metadata_expire
              time in seconds

              The period after which the remote repository is checked
              for metadata update and in the positive case the local
              metadata cache is updated. The default corresponds to 48
              hours. Set this to -1 or never to make the repo never
              considered expired. Expire of metadata can be also
              triggered by change of timestamp of configuration files
              (dnf.conf, <repo>.repo). See also check_config_file_age.

       minrate
              storage size

              This sets the low speed threshold in bytes per second. If
              the server is sending data at the same or slower speed
              than this value for at least timeout option seconds, DNF
              aborts the connection. The default is 1000. Valid units
              are ‘k’, ‘M’, ‘G’.

       password
              string

              The password to use for connecting to a repository with
              basic HTTP authentication. Empty by default.

       proxy  string

              URL of a proxy server to connect through. Set to an empty
              string to disable the proxy setting inherited from the
              main section and use direct connection instead. The
              expected format of this option is
              <scheme>://<ip-or-hostname>[:port].  (For backward
              compatibility, ‘_none_’ can be used instead of the empty
              string.)

              Note: The curl environment variables (such as http_proxy)
              are effective if this option is unset. See the curl man
              page for details.

       proxy_username
              string

              The username to use for connecting to the proxy server.
              Empty by default.

       proxy_password
              string

              The password to use for connecting to the proxy server.
              Empty by default.

       proxy_auth_method
              string

              The authentication method used by the proxy server. Valid
              values are

              Defaults to any

       proxy_sslcacert
              string

              Path to the file containing the certificate authorities to
              verify proxy SSL certificates.  Empty by default - uses
              system default.

       proxy_sslverify
              boolean

              When enabled, proxy SSL certificates are verified. If the
              client can not be authenticated, connecting fails and the
              repository is not used any further. If False, SSL
              connections can be used, but certificates are not
              verified. Default is True.

       proxy_sslclientcert
              string

              Path to the SSL client certificate used to connect to
              proxy server.  Empty by default.

       proxy_sslclientkey
              string

              Path to the SSL client key used to connect to proxy
              server.  Empty by default.

       repo_gpgcheck
              boolean

              Whether to perform GPG signature check on this
              repository’s metadata. The default is False.

       retries
              integer

              Set the number of total retries for downloading packages.
              The number is accumulative, so e.g. for retries=10, dnf
              will fail after any package download fails for eleventh
              time. Setting this to 0 makes dnf try forever. Default is
              10.

       skip_if_unavailable
              boolean

              If enabled, DNF will continue running and disable the
              repository that couldn’t be synchronized for any reason.
              This option doesn’t affect skipping of unavailable
              packages after dependency resolution. To check
              inaccessibility of repository use it in combination with
              refresh command line option. The default is False.  Note
              this option in particular can be set in your configuration
              file by your distribution.

       sslcacert
              string

              Path to the file containing the certificate authorities to
              verify SSL certificates.  Empty by default - uses system
              default.

       sslverify
              boolean

              When enabled, remote SSL certificates are verified. If the
              client can not be authenticated, connecting fails and the
              repository is not used any further. If False, SSL
              connections can be used, but certificates are not
              verified. Default is True.

       sslverifystatus
              boolean

              When enabled, revocation status of the server certificate
              is verified using the “Certificate Status Request” TLS
              extension (aka. OCSP stapling). Default is False.

       sslclientcert
              string

              Path to the SSL client certificate used to connect to
              remote sites.  Empty by default.

       sslclientkey
              string

              Path to the SSL client key used to connect to remote
              sites.  Empty by default.

       throttle
              storage size

              Limits the downloading speed. It might be an absolute
              value or a percentage, relative to the value of the
              bandwidth option option. 0 means no throttling (the
              default). The absolute value is in bytes by default but
              can be specified with a unit of storage. Valid units are
              ‘k’, ‘M’, ‘G’.

       timeout
              time in seconds

              Number of seconds to wait for a connection before timing
              out. Used in combination with minrate option option.
              Defaults to 30 seconds.

       username
              string

              The username to use for connecting to repo with basic HTTP
              authentication. Empty by default.

       user_agent
              string

              The User-Agent string to include in HTTP requests sent by
              DNF.  Defaults to

                 libdnf (NAME VERSION_ID; VARIANT_ID; OS.BASEARCH)

              where NAME, VERSION_ID and VARIANT_ID are OS identifiers
              read from the os-release(5) file, and OS and BASEARCH are
              the canonical OS name and base architecture, respectively.
              Example:

                 libdnf (Fedora 31; server; Linux.x86_64)

       Variables
              Any properly named file in /etc/dnf/vars is turned into a
              variable named after the filename (or overrides any of the
              above variables but those set from commandline). Filenames
              may contain only alphanumeric characters and underscores
