sam2p project sam2p DOWNGRADE

Affected: 0.49.3

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.49.3

1. Check installed version

apt-cache policy sam2p || rpm -q sam2p || sam2p --version

2. No fixed release: DOWNGRADE to a release before 0.49.3 (Debian / Ubuntu)

apt-cache madison sam2p sudo apt install sam2p=<VERSION_BEFORE_0.49.3> sudo apt-mark hold sam2p

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

dnf --showduplicates list sam2p sudo dnf downgrade sam2p-<VERSION_BEFORE_0.49.3> sudo dnf versionlock add sam2p

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.
