canonical metal as a service UPGRADE

Affected: >= 3.1.0 and < 3.1.4 · >= 3.2.0 and < 3.2.11 · >= 3.3.0 and < 3.3.8 · >= 3.4.0 and < 3.4.4 · 3.5.0

Fixed in: 3.1.4, 3.2.11, 3.3.8, 3.4.4

Safe to downgrade to: a release before 3.1.0

1. Check installed version

apt-cache policy metal-as-a-service || rpm -q metal-as-a-service || metal-as-a-service --version

2. UPGRADE to 3.1.4 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade metal-as-a-service

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade metal-as-a-service

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 3.1.0 (Debian / Ubuntu)

apt-cache madison metal-as-a-service sudo apt install metal-as-a-service=<VERSION_BEFORE_3.1.0> sudo apt-mark hold metal-as-a-service

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list metal-as-a-service sudo dnf downgrade metal-as-a-service-<VERSION_BEFORE_3.1.0> sudo dnf versionlock add metal-as-a-service

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.
