YUM2DNF(8)                         DNF                        YUM2DNF(8)

NAME         top

       yum2dnf - Changes in DNF compared to YUM

--SKIP-BROKEN         top

       For install command:

       The --skip-broken option is an alias for --setopt=strict=0. Both
       options could be used with DNF to skip all unavailable packages
       or packages with broken dependencies given to DNF without raising
       an error causing the whole operation to fail. This behavior can
       be set as default in dnf.conf file. See strict conf option.

       For upgrade command:

       The semantics that were supposed to trigger in YUM with
       --skip-broken are now set for plain dnf update as a default.
       There is no need to use --skip-broken with the dnf upgrade
       command. To use only the latest versions of packages in
       transactions, there is the --best command line switch.

UPDATE AND UPGRADE COMMANDS ARE THE SAME         top

       Invoking dnf update or dnf upgrade, in all their forms, has the
       same effect in DNF, with the latter being preferred. In YUM yum
       upgrade was exactly like yum --obsoletes update.

CLEAN_REQUIREMENTS_ON_REMOVE ON BY DEFAULT         top

       The clean_requirements_on_remove switch is on by default in DNF.
       It can thus be confusing to compare the “remove” operation
       results between DNF and YUM as by default DNF is often going to
       remove more packages.

NO RESOLVEDEP COMMAND         top

       The YUM version of this command is maintained for legacy reasons
       only. The user can just use dnf provides to find out what package
       provides a particular file.

NO DEPLIST COMMAND         top

       An alternative to the YUM deplist command to find out
       dependencies of a package is dnf repoquery --deplist using
       repoquery command.

       NOTE:
          Alternatively there is a YUM compatibility support where yum
          deplist is alias for dnf repoquery --deplist command

EXCLUDES AND REPO EXCLUDES APPLY TO ALL OPERATIONS         top

       YUM only respects excludes during installs and upgrades. DNF
       extends this to all operations, among others erasing and listing.
       If you e.g. want to see a list of all installed python-f*
       packages but not any of the Flask packages, the following will
       work:

          dnf -x '*flask*' list installed 'python-f*'

THE INCLUDE OPTION HAS BEEN REMOVED         top

       Inclusion of other configuration files in the main configuration
       file is no longer supported.

DNF PROVIDES /BIN/<FILE> IS NOT FULLY SUPPORTED         top

       After UsrMove there’s no directory /bin on Fedora systems and no
       files get installed there, /bin is only a symlink created by the
       filesystem package to point to /usr/bin. Resolving the symlinks
       to their real path would only give the user a false sense that
       this works, while in fact provides requests using globs such as:

          dnf provides /b*/<file>

       will fail still (as they do in YUM now). To find what provides a
       particular binary, use the actual path for binaries on Fedora:

          dnf provides /usr/bin/<file>

       Also see related Fedora bugzillas 982947 and 982664.

SKIP_IF_UNAVAILABLE COULD BE ENABLED BY DEFAULT         top

       In some distributions DNF is shipped with
       skip_if_unavailable=True in the DNF configuration file. The
       reason for the change is that third-party repositories can often
       be unavailable. Without this setting in the relevant repository
       configuration file YUM immediately stops on a repository
       synchronization error, confusing and bothering the user.

       See the related Fedora bug 984483.

OVERWRITE_GROUPS DROPPED, COMPS FUNCTIONS ACTING AS IF ALWAYS DISABLED

        top

       This config option has been dropped. When DNF sees several groups
       with the same group ID it merges the groups’ contents together.

MIRRORLIST_EXPIRE DROPPED         top

       To simplify things for the user, DNF uses metadata_expire for
       both expiring metadata and the mirrorlist file (which is a kind
       of metadata itself).

METALINK NOT RECOGNIZED IN THE MIRRORLIST REPO OPTION         top

       The following part of yum.conf(5) no longer applies for the
       mirrorlist option:
          As a special hack if the mirrorlist URL contains the word
          “metalink” then the value of mirrorlist is copied to metalink
          (if metalink is not set).

       The relevant repository configuration files have been fixed to
       respect this, see the related Fedora bug 948788.

ALWAYSPROMPT DROPPED         top

       Unsupported to simplify the configuration.

UPGRADE_REQUIREMENTS_ON_INSTALL DROPPED         top

       Dropping this config option with blurry semantics simplifies the
       configuration. DNF behaves as if this was disabled. If the user
       wanted to upgrade everything to the latest version she’d simply
       use dnf upgrade.

DNF HISTORY ROLLBACK CHECK DROPPED         top

       Since DNF tolerates the use of other package managers, it is
       possible that not all changes to the RPMDB are stored in the
       history of transactions. Therefore, DNF does not fail if such a
       situation is encountered and thus the force option is not needed
       anymore.

PACKAGES REPLACEMENT WITHOUT YUM SWAP         top

       Time after time one needs to remove an installed package and
       replace it with a different one, providing the same capabilities
       while other packages depending on these capabilities stay
       installed. Without (transiently) breaking consistency of the
       package database this can be done by performing the remove and
       the install in one transaction. The common way to set up such a
       transaction in DNF is to use dnf shell or use the --allowerasing
       switch.

       E.g. say you want to replace A (providing P)  with B (also
       providing P, conflicting with A) without deleting C (which
       requires P) in the process. Use:

          dnf --allowerasing install B

       This command is equal to yum swap A B.

       DNF provides swap command but only dnf swap A B syntax is
       supported

DEPENDENCY PROCESSING DETAILS ARE NOT SHOWN IN THE CLI         top

       During its depsolving phase, YUM outputs lines similar to:

          ---> Package rubygem-rhc.noarch 0:1.16.9-1.fc19 will be an update
          --> Processing Dependency: rubygem-net-ssh-multi >= 1.2.0 for package: rubygem-rhc-1.16.9-1.fc19.noarch

       DNF does not output information like this. The technical reason
       is that depsolver below DNF always considers all dependencies for
       update candidates and the output would be very long. Secondly,
       even in YUM this output gets confusing very quickly especially
       for large transactions and so does more harm than good.

       See the related Fedora bug 1044999.

DNF PROVIDES COMPLIES WITH THE YUM DOCUMENTATION OF THE COMMAND         top


       When one executes:

          yum provides sandbox

       YUM applies extra heuristics to determine what the user meant by
       sandbox, for instance it sequentially prepends entries from the
       PATH environment variable to it to see if it matches a file
       provided by some package. This is an undocumented behavior that
       DNF does not emulate. Just typically use:

          dnf provides /usr/bin/sandbox

       or even:

          dnf provides '*/sandbox'

       to obtain similar results.

BANDWIDTH LIMITING         top

       DNF supports the throttle and bandwidth options familiar from
       YUM.  Contrary to YUM, when multiple downloads run simultaneously
       the total downloading speed is throttled. This was not possible
       in YUM since downloaders ran in different processes.

INSTALLONLYPKGS CONFIG OPTION         top

       Compared to YUM, DNF appends list values from the installonlypkgs
       config option to DNF defaults, where YUM overwrites the defaults
       by option values.

THE USAGE OF DELTA RPM FILES         top

       The boolean deltarpm option controls whether delta RPM files are
       used. Compared to YUM, DNF does not support deltarpm_percentage
       and instead chooses some optimal value of DRPM/RPM ratio to
       decide whether using deltarpm makes sense in the given case.

HANDLING .SRPM FILES AND NON-EXISTENT PACKAGES         top

       DNF will terminate early with an error if a command is executed
       requesting an installing operation on a local .srpm file:

          $ dnf install fdn-0.4.17-1.fc20.src.rpm tour-4-6.noarch.rpm
          Error: Will not install a source rpm package (fdn-0.4.17-1.fc20.src).

       The same applies for package specifications that do not match any
       available package.

       YUM will only issue a warning in this case and continue
       installing the “tour” package. The rationale behind the result in
       DNF is that a program should terminate with an error if it can
       not fulfill the CLI command in its entirety.

PROMOTING PACKAGE TO INSTALL TO A PACKAGE THAT OBSOLETES IT         top

       DNF will not magically replace a request for installing package X
       to installing package Y if Y obsoletes X. YUM does this if its
       obsoletes config option is enabled but the behavior is not
       properly documented and can be harmful.

       See the related Fedora bug 1096506 and guidelines for renaming
       and obsoleting packages in Fedora.

BEHAVIOR OF --INSTALLROOT OPTION         top

       DNF offers more predictable behavior of installroot. DNF handles
       the path differently from the --config command-line option, where
       this path is always related to the host system (YUM combines this
       path with installroot). Reposdir is also handled slightly
       differently, if one path of the reposdirs exists inside of
       installroot, then repos are strictly taken from installroot (YUM
       tests each path from reposdir separately and use installroot path
       if existed). See the detailed description for --installroot
       option.

DIFFERENT PROMPT AFTER TRANSACTION TABLE         top

       DNF doesn’t provide download functionality after displaying
       transaction table. It only asks user whether to continue with
       transaction or not.  If one wants to download packages, they can
       use the ‘download’ command.

LIST COMMAND SHOWS ALL REPO ALTERNATIVES         top

       DNF lists all packages from all repos, which means there can be
       duplicates package names (with different repo name). This is due
       to providing users possibility to choose preferred repo.

YUM-LANGPACKS SUBCOMMANDS HAVE BEEN REMOVED         top

       Translations became part of core DNF and it is no longer
       necessary to manage individual language packs.

       Following sub-commands were removed:

       • langavailable

       • langinstall

       • langremove

       • langlist

       • langinfo

YUM-UPDATEONBOOT AND YUM-CRON         top

       DNF does not have a direct replacement of yum-updateonboot and
       yum-cron commands.  However, the similar result can be achieved
       by dnf automatic command (see automatic).

       You can either use the shortcut:

          $ systemctl enable --now dnf-automatic-install.timer

       Or set apply_updates option of /etc/dnf/automatic.conf to True
       and use generic timer unit:

          $ systemctl enable --now dnf-automatic.timer

       The timer in both cases is activated 1 hour after the system was
       booted up and then repetitively once every 24 hours. There is
       also a random delay on these timers set to 5 minutes. These
       values can be tweaked via dnf-automatic*.timer config files
       located in the /usr/lib/systemd/system/ directory.

UTILITIES THAT HAVE NOT BEEN PORTED YET         top

       repo-rss, show-changed-rco, show-installed, verifytree,
       yum-groups-manager

       Take a look at the FAQ about YUM to DNF migration. Feel free to
       file an RFE for missing functionality if you need it.
