watchguard authentication gateway UPGRADE

Affected: >= 4.2.2 and < 7.5.1

Fixed in: 7.5.1

Safe to downgrade to: a release before 4.2.2

1. Check installed version

apt-cache policy authentication-gateway || rpm -q authentication-gateway || authentication-gateway --version

2. UPGRADE to 7.5.1 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade authentication-gateway

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade authentication-gateway

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 4.2.2 (Debian / Ubuntu)

apt-cache madison authentication-gateway sudo apt install authentication-gateway=<VERSION_BEFORE_4.2.2> sudo apt-mark hold authentication-gateway

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list authentication-gateway sudo dnf downgrade authentication-gateway-<VERSION_BEFORE_4.2.2> sudo dnf versionlock add authentication-gateway

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.
