apt-cache policy site-server || rpm -q site-server || site-server --version

2. No fixed release: DOWNGRADE to a release before 3.0 (Debian / Ubuntu)

dnf --showduplicates list site-server sudo dnf downgrade site-server-<VERSION_BEFORE_3.0> sudo dnf versionlock add site-server

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.
