e-merge unace DOWNGRADE

Affected: 1.2b

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.2b

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 1.2b (Debian / Ubuntu)

apt-cache madison unace sudo apt install unace=<VERSION_BEFORE_1.2b> sudo apt-mark hold unace

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

dnf --showduplicates list unace sudo dnf downgrade unace-<VERSION_BEFORE_1.2b> sudo dnf versionlock add unace

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.
