redhat multicluster engine for kubernetes DOWNGRADE

Affected: 2.1 · 2.7

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.1

1. Check installed version

apt-cache policy multicluster-engine-for-kubernetes || rpm -q multicluster-engine-for-kubernetes || multicluster-engine-for-kubernetes --version

2. No fixed release: DOWNGRADE to a release before 2.1 (Debian / Ubuntu)

apt-cache madison multicluster-engine-for-kubernetes sudo apt install multicluster-engine-for-kubernetes=<VERSION_BEFORE_2.1> sudo apt-mark hold multicluster-engine-for-kubernetes

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

dnf --showduplicates list multicluster-engine-for-kubernetes sudo dnf downgrade multicluster-engine-for-kubernetes-<VERSION_BEFORE_2.1> sudo dnf versionlock add multicluster-engine-for-kubernetes

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.
