google gerrit DOWNGRADE

Affected: >= 2.12

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.12

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 2.12 (Debian / Ubuntu)

apt-cache madison gerrit sudo apt install gerrit=<VERSION_BEFORE_2.12> sudo apt-mark hold gerrit

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list gerrit sudo dnf downgrade gerrit-<VERSION_BEFORE_2.12> sudo dnf versionlock add gerrit

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.
