=== Upgrading ===

A new major version of Fedora happens is released six months, approximately in April and October. Major version releases are supported for 13 months.

A host running Fedora can be upgraded in steps of 1 or 2 major version releases.

 1. Update all software and reboot
 2. Download the new release

{{{
sudo dnf install dnf-plugin-system-upgrade
sudo dnf system-upgrade download --releasever=40
}}}

The download may be blocked if support for some software was dropped. The `--allowerasing` option can be passed to force the download anyway.

 3.#3 Validate the GPG fingerprint that is printed to the screen
 4. Trigger the upgrade and reboot sequence

{{{
sudo dnf system-upgrade reboot
}}}

If system won't boot, try to rescue boot and check the system journal.

If system boots into a non-updated release, are you running on a Raspberry Pi or some other platform that may not have a perfectly functional system clock? There's a [[https://bugzilla.redhat.com/show_bug.cgi?id=2242759#c41|wontfix bug]] and the best solution is to `sudo touch /usr/lib/clock-epoch`.

 5.#5 Clean up after a successful boot

{{{
sudo dnf system-upgrade clean
sudo dnf clean packages
}}}

 6.#6 If it was not done in step 2, erase unsupported software

{{{
sudo dnf install remove-retired-packages
remove-retired-packages
sudo dnf repoquery --unsatisfied
}}}
