cybozu garoon UPGRADE

Affected: >= 5.5.0 and < 6.0.1

Fixed in: 6.0.1

Safe to downgrade to: a release before 5.5.0

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

dnf --showduplicates list garoon sudo dnf downgrade garoon-<VERSION_BEFORE_5.5.0> sudo dnf versionlock add garoon

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.
