grafana grafana UPGRADE

Affected: >= 8.0.0 and <= 12.3.0

Fixed in: newer than 12.3.0

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 8.0.0 (Debian / Ubuntu)

apt-cache madison grafana sudo apt install grafana=<VERSION_BEFORE_8.0.0> sudo apt-mark hold grafana

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

dnf --showduplicates list grafana sudo dnf downgrade grafana-<VERSION_BEFORE_8.0.0> sudo dnf versionlock add grafana

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.
