DNF4.CONF(5) DNF DNF4.CONF(5)
dnf4.conf - DNF Configuration Reference
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.
Configuration options, namely best and skip_if_unavailable, can
be set in the DNF configuration file by your distribution to
override the DNF defaults.
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.
API Notes: Must be set before repository objects are
created. Plugins must set this in the pre_config hook.
Later changes are ignored.
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 whether rpm should 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.
exclude_from_weak
list
Prevent installing packages as weak dependencies
(recommends or supplements). The packages can be specified
by a name or a glob and separated by a comma. Defaults to
[].
exclude_from_weak_autodetect
boolean
If enabled, dnf will autodetect unmet weak dependencies
(recommends or supplements) of packages installed on the
system. Providers of these weak dependencies will not be
installed by dnf as weak dependencies any more (they will
still be installed if pulled in as a regular dependency).
Defaults to true.
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 explicitly 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. Default is False.
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. Default is False.
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 packages for all
available 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
optional_metadata_types
list
List of metadata types to be loaded in addition to
primary, modules, comps, updateinfo and presto, which are
loaded always.
Note that the list can be extended by individual commands
to explicitly request loading specific metadata type.
Currently only filelists value is supported. Default is an
empty list.
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.
The $releasever_major and $releasever_minor variables will
be automatically derived from $releasever by splitting it
on the first .. For example, if $releasever is set to
1.23, then $releasever_major will be 1 and
$releasever_minor will be 23.
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 │
├──────────────┼────────────────────────────┤
│ noscripts │ RPMTRANS_FLAG_NOSCRIPTS │
├──────────────┼────────────────────────────┤
│ test │ RPMTRANS_FLAG_TEST │
├──────────────┼────────────────────────────┤
│ notriggers │ RPMTRANS_FLAG_NOTRIGGERS │
├──────────────┼────────────────────────────┤
│ nodocs │ RPMTRANS_FLAG_NODOCS │
├──────────────┼────────────────────────────┤
│ justdb │ RPMTRANS_FLAG_JUSTDB │
├──────────────┼────────────────────────────┤
│ nocontexts │ RPMTRANS_FLAG_NOCONTEXTS │
├──────────────┼────────────────────────────┤
│ nocaps │ RPMTRANS_FLAG_NOCAPS │
├──────────────┼────────────────────────────┤
│ nocrypto │ RPMTRANS_FLAG_NOFILEDIGEST │
├──────────────┼────────────────────────────┤
│ deploops │ RPMTRANS_FLAG_DEPLOOPS │
└──────────────┴────────────────────────────┘
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.
color string
Controls if DNF uses colored output on the command line.
Possible values: "auto", "never", "always". Default is
"auto".
color_list_available_downgrade
color
Color of available packages that are older than installed
packages. The option is used during list operations.
Default is magenta.
color_list_available_install
color
Color of packages that are available for installation and
none of their versions in installed. The option is used
during list operations. Default is bold,cyan.
color_list_available_reinstall
color
Color of available packages that are identical to
installed versions and are available for reinstalls.
Default is bold,underline,green. The option is used
during list operations.
color_list_available_upgrade
color
Color of available packages that are newer than installed
packages. Default is bold,blue. The option is used during
list operations.
color_list_installed_extra
color
Color of installed packages that do not have any version
among available packages. The option is used during list
operations. Default is bold,red.
color_list_installed_newer
color
Color of installed packages that are newer than any
version among available packages. The option is used
during list operations. Default is bold,yellow.
color_list_installed_older
color
Color of installed packages that are older than any
version among available packages. The option is used
during list operations. Default is yellow.
color_list_installed_reinstall
color
Color of installed packages that are among available
packages and can be reinstalled. The option is used
during list operations. Default is cyan.
color_search_match
color
Color of patterns matched in search output. Default is
bold,magenta.
color_update_installed
color
Color of removed packages. Default is red. This option is
used during displaying transactions.
color_update_local
color
Color of local packages that are installed from the
@commandline repository. This option is used during
displaying transactions. Default is green.
color_update_remote
color
Color of packages that are installed/upgraded/downgraded
from remote repositories. This option is used during
displaying transactions. Default is bold,green.
baseurl
list
List of URLs for the repository. Defaults to [].
URLs are tried in the listed order (equivalent to yum's
"failovermethod=priority" behaviour).
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.
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.
$releasever_major
Major version of $releasever, i.e. the component of
$releasever occurring before the first ..
$releasever_minor
Minor version of $releasever, i.e. the component of
$releasever occurring after the first ..
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
A limited form of shell-like parameter expansion is supported for
variables.
${my_variable:-word} If my_variable is unset or empty, then word
will be substituted. Otherwise, the value of my_variable will be
substituted.
${my_variable:+word} If my_variable is set and not empty, then
word will be substituted. Otherwise, the empty string will be
substituted.
Parameter expansions can be nested up to a maximum depth of 32.
For example:
${my_defined_variable:+${my_undefined_variable:-foobar}}
will evaluate to foobar.
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
When enabled, one (and only one) HTTP GET request for the
metalink file will be selected at random every week to
carry a special URL flag.
This flag allows the repository provider to estimate the
number of systems consuming the repository, by counting
such requests over a week's time. This method is more
accurate than just counting unique IP addresses (which is
subject to both overcounting and undercounting due to
short DHCP leases and NAT, respectively).
This is not an out-of-band HTTP request made for this
purpose alone. Only requests initiated by DNF during
normal operation, such as to check for metadata updates,
can get this flag.
The flag is a simple "countme=N" parameter appended to the
metalink URL where N is an integer representing the age
"bucket" this system belongs to. Four buckets are
defined, based on how many full weeks have passed since
the installation of a system:
┌────────┬──────────────────────────┐
│ bucket │ system age │
├────────┼──────────────────────────┤
│ 1 │ first week │
├────────┼──────────────────────────┤
│ 2 │ first month (2 - 4 │
│ │ weeks) │
├────────┼──────────────────────────┤
│ 3 │ first 6 months (5 - 24 │
│ │ weeks) │
├────────┼──────────────────────────┤
│ 4 │ more than 6 months (> 24 │
│ │ weeks) │
└────────┴──────────────────────────┘
This number is meant to help distinguish short-lived
(throwaway) machines from long-term installs and get a
better picture of how systems are used over time.
To determine a system's installation time ("epoch"), the
machine-id(5) file's modification time is used as the
single source of truth. This file is semantically tied to
the system's lifetime as it's typically populated at
installation time or during the first boot by an installer
tool or init system (such as systemd(1)), respectively,
and remains unchanged.
If the file is empty or missing (such as in containers),
the time of the very first request made using the expanded
metalink URL (i.e. with any repository variables such as
$releasever substituted) that carried the flag is declared
as the epoch.
If no metalink URL is defined for this repository but a
mirrorlist URL is, the latter is used for this purpose
instead.
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
False. It requires /usr/bin/applydeltarpm on the system.
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 in the repository configuration to disable proxy
setting inherited from the main section. 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 (or '_none_' is set
in the repository configuration). 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
┌───────────┬──────────────────────────┐
│ method │ meaning │
├───────────┼──────────────────────────┤
│ basic │ HTTP Basic │
│ │ authentication │
├───────────┼──────────────────────────┤

└───────────┴──────────────────────────┘
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. Note that
GPG keys for this check are stored separately from GPG
keys used in package signature verification. Furthermore,
they are also stored separately for each repository.
This means that dnf may ask to import the same key
multiple times. For example, when a key was already
imported for package signature verification and this
option is turned on, it may be needed to import it again
for the repository.
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.

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

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'.

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.

authentication. Empty by default.
