DNF versionlock Plugin¶
versionlock is a plugin that takes a set of names and versions for packages and excludes all other versions of those packages. This allows you to protect packages from being updated by newer versions. Alternately, it accepts a specific package version to exclude from updates, e.g. for when it’s necessary to skip a specific release of a package that has known issues.
The plugin provides a command versionlock which allows you to view and edit the list of locked packages easily.
The plugin will walk each line of the versionlock file, and parse out the name and version of the package. It will then exclude any package by that name that doesn’t match one of the versions listed within the file. This is basically the same as using dnf –exclude for the package name itself (as you cannot exclude installed packages), but dnf will still see the versions you have installed/versionlocked as available so that dnf reinstall will still work, etc.
It can also work in the opposite way, like a fast exclude, by prefixing a ‘!’ character to the version recorded in the lock list file. This specifically excludes a package that matches the version exactly.
Note the versionlock plugin does not apply any excludes in non-transactional operations like repoquery, list, info, etc.
dnf versionlock [options] [add|exclude|list|delete|clear] [<package-name-spec>]
- Package spec to lock or exclude.
dnf versionlock add <package-name-spec>
Add a versionlock for all available packages matching the spec. It means that only versions of packages represented by
<package-name-spec>will be available for transaction operations. Each
<package-name-spec>is converted to concrete NEVRAs which are used for locking. The NEVRAs to lock to are first searched among installed packages and then (if none is found) in all currently available packages.
Locking a package to the version installed: $ dnf repoquery --installed bash bash-0:5.0.7-1.fc30.x86_64 $ dnf repoquery bash bash-0:5.0.2-1.fc30.i686 bash-0:5.0.2-1.fc30.x86_64 bash-0:5.0.7-1.fc30.i686 bash-0:5.0.7-1.fc30.x86_64 $ dnf versionlock add bash Adding versionlock on: bash-0:5.0.7-1.fc30.* Locking not installed package to any of available versions: $ dnf repoquery --installed mutt $ dnf repoquery mutt mutt-5:1.11.4-1.fc30.x86_64 mutt-5:1.12.1-3.fc30.x86_64 $ dnf versionlock add mutt Adding versionlock on: mutt-5:1.11.4-1.fc30.* Adding versionlock on: mutt-5:1.12.1-3.fc30.*
Be careful when adding specific versions
If you add a package specifying a version with
dnf versionlock mutt-5:1.11.4-1.fc30.x86_64then, if you run
dnf versionlock add muttversionlock will not add
dnf versionlock exclude <package-name-spec>
- Add an exclude (within versionlock) for the available packages matching the spec. It means that
packages represented by
<package-name-spec>will be excluded from transaction operations.
dnf versionlock listor
- List the current versionlock entries.
dnf versionlock delete <package-name-spec>
- Remove any matching versionlock entries.
dnf versionlock clear
- Remove all versionlock entries.
All general DNF options are accepted, see Options in dnf(8) for details.
Do not resolve
<package-name-spec>to NEVRAs to find specific version to lock to. Instead
<package-name-spec>are used as they are. This enables locking to not yet available versions of the package. For example you may want to keep the bash package on major version 5 and consume any future updates as far as they keep the major version:
$ dnf versionlock add --raw 'bash-5.*' Adding versionlock on: bash-5.*
The minimal content of conf file should contain
main sections with
This option is a string that points to the file which has the versionlock information in it. Note that the file has to exist (or the versionlock plugin will make dnf exit). However, it can be empty.
The file takes entries in the format of
<package-name-spec>(optionally prefixed with ‘!’ for excludes). See Specifying packages in dnf(8) for details.
A specified package does not have to exist within the available cache of repository data
to be considered valid for locking or exclusion. This is by design, to accommodate use
cases such as a presently disabled repository. However, a package must exist in the
repository cache when the
exclude subcommands are invoked for it.
