gitlab gitlab UPGRADE

Affected: >= 13.8.0 and < 19.2.8 · >= 19.3.0 and < 19.3.5 · >= 19.4.0 and < 19.4.2

Fixed in: 19.2.8, 19.3.5, 19.4.2

Safe to downgrade to: a release before 13.8.0

2. UPGRADE to 19.2.8 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade gitlab

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 13.8.0 (Debian / Ubuntu)

apt-cache madison gitlab sudo apt install gitlab=<VERSION_BEFORE_13.8.0> sudo apt-mark hold gitlab

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

dnf --showduplicates list gitlab sudo dnf downgrade gitlab-<VERSION_BEFORE_13.8.0> sudo dnf versionlock add gitlab

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.
