cloudogu scm manager UPGRADE

Affected: >= 1.2 and <= 1.60

Fixed in: newer than 1.60

Safe to downgrade to: a release before 1.2

1. Check installed version

apt-cache policy scm-manager || rpm -q scm-manager || scm-manager --version

Note

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

apt-cache madison scm-manager sudo apt install scm-manager=<VERSION_BEFORE_1.2> sudo apt-mark hold scm-manager

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

dnf --showduplicates list scm-manager sudo dnf downgrade scm-manager-<VERSION_BEFORE_1.2> sudo dnf versionlock add scm-manager

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.
