Atomic rollback

Rolling back

Fedora Silverblue keeps a record of the previous OS version, which can be switched to instead of the latest version. While this shouldn’t usually be necessary, it can be helpful if there is a problem with an update or an upgrade (rollbacks work the same way for both), as well as for development purposes.

There are two ways to roll back to the previous version:

1. Temporary rollbacks: to temporarily roll back to a previous version, simply reboot and select the previous version from the boot menu (often known as the grub menu).
2. Permanent rollbacks: to permanently switch back to the previous deployment, use the rpm-ostree rollback command.

After rolling back, you will technically be on an old OS version, and may be prompted to update. Updating will undo the rollback, so should be avoided if you want the rollback to stay in effect.

rpm-ostree only keeps one rollback version available by default. If you want to rollback to another version than the one currently available on your system, you can do so with the following commands:

1. Pull the ostree commit log from the remote repository: $ sudo ostree pull --commit-metadata-only --depth=10 fedora fedora/41/x86_64/silverblue

Display the log:

$ ostree log fedora:fedora/41/x86_64/silverblue

Deploy a specific commit:

$ rpm-ostree deploy 41.20230716.0

Note that this will deploy the exact version as requested and will not include overlayed packages and other changes.

Adding and removing COPR repo
Enable your repository:

$ sudo dnf copr enable your_name/test-project

And install the package:

$ sudo dnf install package

To uninstall your package:

$ sudo dnf remove package

And to disable your repository:

$ sudo dnf copr disable your_name/test-project

TO remove unused rpm but not removed the configuration file

dnf autoremove

HOLDING PACKAGE

You can also use the DNF versionlock plugin to limit the packages that are included in a transaction. It allows you to list what versions of particular packages should be considered in a transaction. All other versions of the specified packages will be ignored. The plugin is part of dnf-plugins-core package and can be installed using the command below:

sudo dnf install 'dnf-command(versionlock)'

To lock the currently installed version of a package, use:

sudo dnf versionlock add package

To remove the version lock, use:

sudo dnf versionlock delete package

Lastly recommend dnf config.

cat /etc/dnf/dnf.conf 
# see `man dnf.conf` for defaults and possible options

fastestmirror=true
max_parallel_downloads=5
# exclude="packagename"
# exclude="*lib*" exclude with wildcard
