openeclass openeclass UPGRADE

Affected: >= 3.11 and < 3.13

Fixed in: 3.13

Safe to downgrade to: a release before 3.11

1. Check installed version

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

2. UPGRADE to 3.13 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade openeclass

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade openeclass

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 3.11 (Debian / Ubuntu)

apt-cache madison openeclass sudo apt install openeclass=<VERSION_BEFORE_3.11> sudo apt-mark hold openeclass

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

dnf --showduplicates list openeclass sudo dnf downgrade openeclass-<VERSION_BEFORE_3.11> sudo dnf versionlock add openeclass

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.
