sos-berlin jobscheduler UPGRADE

Affected: >= 1.12.0 and <= 1.12.12 · >= 1.13.0 and <= 1.13.3

Fixed in: newer than 1.13.3

Safe to downgrade to: a release before 1.12.0

1. Check installed version

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

2. UPGRADE to newer than 1.13.3 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade jobscheduler

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 1.12.0 (Debian / Ubuntu)

apt-cache madison jobscheduler sudo apt install jobscheduler=<VERSION_BEFORE_1.12.0> sudo apt-mark hold jobscheduler

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

dnf --showduplicates list jobscheduler sudo dnf downgrade jobscheduler-<VERSION_BEFORE_1.12.0> sudo dnf versionlock add jobscheduler

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.
