clanlib clanlib DOWNGRADE

Affected: 0.5

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.5

1. Check installed version

apt-cache policy clanlib || rpm -q clanlib || clanlib --version

2. No fixed release: DOWNGRADE to a release before 0.5 (Debian / Ubuntu)

apt-cache madison clanlib sudo apt install clanlib=<VERSION_BEFORE_0.5> sudo apt-mark hold clanlib

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list clanlib sudo dnf downgrade clanlib-<VERSION_BEFORE_0.5> sudo dnf versionlock add clanlib

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.
