Note

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

3. If no update is available yet, DOWNGRADE to a release before 22.04.0 (Debian / Ubuntu)

apt-cache madison centreon sudo apt install centreon=<VERSION_BEFORE_22.04.0> sudo apt-mark hold centreon

dnf --showduplicates list centreon sudo dnf downgrade centreon-<VERSION_BEFORE_22.04.0> sudo dnf versionlock add centreon

Downgrade risk

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

After downgrade

Restart the service, and keep the package held until a fixed release ships.
