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
Upgrading between major versions (such as from Fedora {version-oldstable} to Fedora {version-stable}) can be completed using the {update-application} application. Alternatively, {variant-name} can be upgraded between major versions using the `rpm-ostree` command.
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 {version-oldstable} to {version-stable}, 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 {variant-name} with this command:
$ ostree remote refs fedora | grep {variant} | grep $(uname -m)
After you've verified the name of your branch, you are ready to proceed. For example, to upgrade to {variant-name} {version-stable}, the command is:
$ rpm-ostree rebase fedora:fedora/{version-stable}/x86_64/{variant}
Currently, the default remote for {variant-name} {version-stable} is named `fedora`.
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 {alternative-name}. {alternative-name} is similar to {variant-name}, except for the fact that it uses the {alternative-desktop} instead of the default {variant-desktop}.
What this means is, you can rebase to {alternative-name} 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 {variant-name}, which is Rawhide.
If you decide to rebase, make sure to xref:faq.adoc#pinning[pin] your current deployment, so you don't accidentaly lose it (by default, only the two most recent deployments are kept).
Rolling back
{variant-name} 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 `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:
Pull the ostree commit log from the remote repository:
$ sudo ostree pull --commit-metadata-only --depth=10 fedora fedora/{version-stable}/x86_64/{variant}
Display the log:
$ ostree log fedora:fedora/{version-stable}/x86_64/{variant}
Deploy a specific commit:
$ rpm-ostree deploy {version-stable}.20230716.0
