Fedora aktualisieren

Bei einem Upgrade über mehrere Major-Releases sollte schrittweise aktualisiert werden. Fedora testet und unterstützt ein Upgrade über zwei Versionen (z.B. von 41 auf 43), dies wird jedoch nicht empfohlen. Die Downtime beträgt auf einem minimalen Fedora-Server zwischen 10 und 20 Minuten.

Warnung

Vor dem Upgrade unbedingt einen Snapshot oder ein Backup erstellen und die Release Notes lesen.

dnf versionlock clear
# Otherwise the update will fail

# Make sure the server is up-to-date
dnf --assumeyes upgrade --refresh
reboot

# Download and install the update
VER=43
dnf system-upgrade download --releasever=$VER --refresh
dnf5 offline reboot

cat /etc/os-release

Nach dem Upgrade aufräumen

dnf install rpmconf remove-retired-packages clean-rpm-gpg-pubkey

# Find and manage all .rpmnew and .rpmsave files
rpmconf -a
# Remove packages that are no longer available in Fedora
remove-retired-packages
# Remove old GPG keys
clean-rpm-gpg-pubkey
# Find dangling symlinks
symlinks -r /usr | grep dangling
# Remove dangling symlinks
symlinks -r -d /usr

dnf remove rpmconf remove-retired-packages clean-rpm-gpg-pubkey

# Find packages with multiple versions
dnf repoquery --duplicates
# If they have to be removed
dnf remove --duplicates
# List installed packages not in Fedora repos
dnf list --extras

# Check logs and failed units
journalctl --boot
systemctl list-units --state=failed
# When everything is done
systemctl reboot

Falls nach dem Upgrade Probleme auftreten sollten (Fehler beim Ausführen von dnf oder rpm, Dependency-Probleme, SELinux-Meldungen), siehe https://docs.fedoraproject.org/en-US/quick-docs/upgrading-fedora-offline/#sect-resolving-post-upgrade-issues
