easy software products cups DOWNGRADE

Affected: 1.1.17 · 1.1.22

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.1.17

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 1.1.17 (Debian / Ubuntu)

apt-cache madison cups sudo apt install cups=<VERSION_BEFORE_1.1.17> sudo apt-mark hold cups

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

dnf --showduplicates list cups sudo dnf downgrade cups-<VERSION_BEFORE_1.1.17> sudo dnf versionlock add cups

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.
