Updates, Upgrades & Rollbacks
Installing updates with Fedora Kinoite is easy and fast. It also has a special rollback feature, in case anything goes wrong. Additionally, you can choose to have multiple versions of your operating system installed at all times, and you can choose which one to boot into whenever you start up your system.
Support for updates in Plasma Discover is available by default starting with the Fedora 38 release. For previous releases, you need to update your system first via the command line to get full support in Plasma Discover.
OS updates are fully integrated into the desktop; you will be automatically notified when an update is available. The default behavior is to only notify about new available updates. You can then install them with Plasma Discover.
You can enable auto-updates in the Plasma Discover settings. In the future, updates will be enabled and installed by default in the background. See the Fedora Change page for more details.
Once an update is ready, it is just a matter of rebooting to start using the new version. There is no waiting for the update to be installed during this reboot.
If you’d prefer, it is also possible to update using the command line. To do this, run:
$ rpm-ostree upgrade
This will check for new updates and download and install them if they are available. Alternatively, to check for available updates without downloading them, run:
$ rpm-ostree upgrade --check
Upgrading between major versions (such as from Fedora 38 to Fedora 39) can be completed using the Plasma Discover application.
Alternatively, Fedora Kinoite can be upgraded between major versions using the
Skipping major releases is currently untested and is thus not supported. You should update only one major release at a time, i.e. from Fedora 38 to 39, etc.
First, make sure that you are running the latest update for the current version:
$ rpm-ostree upgrade
Reboot your system if needed. Then, verify that the branch for the next major version is available. You can print all available branches for Fedora Kinoite with this command:
$ ostree remote refs fedora | grep kinoite | grep $(uname -m)
After you’ve verified the name of your branch, you are ready to proceed. For example, to upgrade to Fedora Kinoite 39, the command is:
$ rpm-ostree rebase fedora:fedora/39/x86_64/kinoite
Currently, the default remote for Fedora Kinoite 39 is named
If this is not the case for your system, you can find out the remote name by issuing:
ostree remote list.
The process is very similar to a system update: the new OS is downloaded and installed in the background, and you just boot into it when it is ready.
Additionally, you can choose to rebase to a different immutable variant of Fedora, like for example Fedora Silverblue. Fedora Siverblue is similar to Fedora Kinoite, except for the fact that it uses the GNOME desktop environment instead of the default Plasma desktop environment.
What this means is, you can rebase to Fedora Silverblue to try it out, without ever touching your current system. Because the two system images are isolated from eachother, the two desktop environments will never be installed at the same time. All of your flatpak apps and /home files will stay persistent between rebases. Same applies for testing out the bleeding-edge version of Fedora Kinoite, which is Rawhide.
If you decide to rebase, make sure to pin your current deployment, so you don’t accidentaly lose it (by default, only the two most recent deployments are kept).
Fedora Kinoite 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:
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).
Permanent rollbacks: to permanently switch back to the previous deployment, use the
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 that the one currently available on your system, you can do so with the following commands:
Pull the ostree commit log from the remote repository:
$ sudo ostree pull --commit-metadata-only --depth=10 fedora fedora/39/x86_64/kinoite
Display the log:
$ ostree log fedora:fedora/39/x86_64/kinoite
Deploy a specific commit:
$ rpm-ostree deploy 39.20230716.0
Note that this will deploy the exact version as requested and will not include overlayed packages and other changes.
