Fixed in: no fixed release known

Safe to downgrade to: a release before 3.20

1. Check installed version

apt-cache policy quake-ii-server-linux || rpm -q quake-ii-server-linux || quake-ii-server-linux --version

2. No fixed release: DOWNGRADE to a release before 3.20 (Debian / Ubuntu)

apt-cache madison quake-ii-server-linux sudo apt install quake-ii-server-linux=<VERSION_BEFORE_3.20> sudo apt-mark hold quake-ii-server-linux

dnf --showduplicates list quake-ii-server-linux sudo dnf downgrade quake-ii-server-linux-<VERSION_BEFORE_3.20> sudo dnf versionlock add quake-ii-server-linux

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.
