zoneminder zoneminder DOWNGRADE

Affected: 1.36.34

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.36.34

dnf --showduplicates list zoneminder sudo dnf downgrade zoneminder-<VERSION_BEFORE_1.36.34> sudo dnf versionlock add zoneminder

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.
