apt-cache madison command-centre sudo apt install command-centre=<VERSION_BEFORE_9.30.1594> sudo apt-mark hold command-centre

dnf --showduplicates list command-centre sudo dnf downgrade command-centre-<VERSION_BEFORE_9.30.1594> sudo dnf versionlock add command-centre

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.
