DNF package manager
DNF is a package manager for RPM systems to install, update and remove packages. DNF was forked from Yum. Among the many improvements, it uses libsolv as a dependency resolver. DNF features support for plugins - which can be used to extend the core functionality of DNF -, automatic updates and parallel package downloads.
On Leap 15.3 and on Tumbleweed DNF is available from the official repositories and can be installed without adding another repository.
on the command line
# zypper install dnf rpm-repos-openSUSE
Start YaST2, select "Software Management" and search for DNF. Select DNF and rpm-repos-openSUSE and mark it for installation and press Accept.
Use DNF as PackageKit backend
If you want to use DNF as backend for PackageKit, use this command:
# dnf swap PackageKit-backend-zypp PackageKit-backend-dnf
To refresh repos:
# dnf makecache
To install packages:
# dnf install packagename
To search the repositories for a package type:
# dnf search packagename
To remove a package:
# dnf remove packagename
Other common DNF commands include
autoremove - removes packages installed as dependencies that are no longer required by currently installed programs.
check-update - checks for updates, but does not download or install the packages.
downgrade - reverts to the previous version of a package.
info - provides basic information about the package including name, version, release, and description.
reinstall - reinstalls the currently installed package.
upgrade - checks the repositories for newer packages and updates them.
exclude - exclude a package from the transaction.
For example to update a Tumbleweed installation:
# dnf makecache # dnf distro-sync
To update a Leap installation:
# dnf makecache # dnf upgrade
This is the equivalent of:
# zypper refresh # zypper dist-upgrade
# zypper refresh # zypper update
openSUSE flavored DNF
DNF on openSUSE also offers some aliases to mimic zypper commands. These aliases can be listed:
# dnf alias
Which will output something like this:
Alias dup='distro-sync' Alias dist-upgrade='distro-sync' Alias ref='makecache' Alias refresh='makecache' Alias ri='reinstall'
Using these aliases one can update the system or refresh repos like in zypper with:
# dnf ref # dnf dup
which are equivalent of:
# zypper ref # zypper dup
To add a new alias for example for remove:
# dnf alias add rm=remove
DNF in this sense is very similar to zypper in a sense that it has to be pointed to .repo file. The command:
# dnf config-manager --add-repo URL
To add a repository from OBS you would have to replace the zypper addrepo part with dnf config-manager --add-repo and the url at the end.
# dnf config-manager --add-repo https://download.opensuse.org/repositories/devel:languages:python/openSUSE_Tumbleweed/devel:languages:python.repo
# dnf repolist
# dnf repolist all
These command will list the unique id and the name of the available repositories. dnf repolist all will add an extra status field after every repository listed indicating that the repository is enabled or disabled.
Before enabling or disabling a repository it is best to list all out with their current status
# dnf repolist all
Then using the id of the repository you wish to enable:
# dnf config-manager --set-enabled repo_id
Or to disable:
# dnf config-manager --set-disabled repo_id
DNF dup can't update the kernel
Currently DNF is marking the kernel packages as protected and in case of a kernel update - which is fairly frequent on Tumbleweed - it will refuse to update. To get around the issue disable the running kernel protection:
# dnf --setopt=protect_running_kernel=False --refresh distro-sync
protect_running_kernel: Controls whether the package corresponding to the running version of kernel is protected from removal. Default is True.
DNF does not have the same integration with OpenSUSE as zypper does without additional plugins
Specific functionality that is enabled by default with zypper can not be reproduced using DNF without the additional installation of plugins. Functionality such as "protected" packages and snapper integration require the use of plugins. To see a list of plugins available search for:
refer to the upstream documentation for up to date information about the plugins.
