mandrakesoft mandrake multi network firewall DOWNGRADE

Affected: 8.2

Fixed in: no fixed release known

Safe to downgrade to: a release before 8.2

1. Check installed version

apt-cache policy mandrake-multi-network-firewall || rpm -q mandrake-multi-network-firewall || mandrake-multi-network-firewall --version

2. No fixed release: DOWNGRADE to a release before 8.2 (Debian / Ubuntu)

apt-cache madison mandrake-multi-network-firewall sudo apt install mandrake-multi-network-firewall=<VERSION_BEFORE_8.2> sudo apt-mark hold mandrake-multi-network-firewall

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

dnf --showduplicates list mandrake-multi-network-firewall sudo dnf downgrade mandrake-multi-network-firewall-<VERSION_BEFORE_8.2> sudo dnf versionlock add mandrake-multi-network-firewall

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.
