eventum project eventum UPGRADE

Affected: >= 3.5.0 and < 3.5.2

Fixed in: 3.5.2

Safe to downgrade to: a release before 3.5.0

1. Check installed version

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

2. UPGRADE to 3.5.2 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

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 3.5.0 (Debian / Ubuntu)

apt-cache madison eventum sudo apt install eventum=<VERSION_BEFORE_3.5.0> sudo apt-mark hold eventum

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

dnf --showduplicates list eventum sudo dnf downgrade eventum-<VERSION_BEFORE_3.5.0> sudo dnf versionlock add eventum

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.
