inspur clusterengine DOWNGRADE

Affected: 4.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 4.0

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 4.0 (Debian / Ubuntu)

apt-cache madison clusterengine sudo apt install clusterengine=<VERSION_BEFORE_4.0> sudo apt-mark hold clusterengine

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

dnf --showduplicates list clusterengine sudo dnf downgrade clusterengine-<VERSION_BEFORE_4.0> sudo dnf versionlock add clusterengine

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.
