mingsoft mcms DOWNGRADE

Affected: 5.5.0 · 6.0.1

Fixed in: no fixed release known

Safe to downgrade to: a release before 5.5.0

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

2. No fixed release: DOWNGRADE to a release before 5.5.0 (Debian / Ubuntu)

apt-cache madison mcms sudo apt install mcms=<VERSION_BEFORE_5.5.0> sudo apt-mark hold mcms

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

dnf --showduplicates list mcms sudo dnf downgrade mcms-<VERSION_BEFORE_5.5.0> sudo dnf versionlock add mcms

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.
