cleanuparr project cleanuparr UPGRADE

Affected: >= 2.7.0 and < 2.8.1

Fixed in: 2.8.1

Safe to downgrade to: a release before 2.7.0

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 2.7.0 (Debian / Ubuntu)

apt-cache madison cleanuparr sudo apt install cleanuparr=<VERSION_BEFORE_2.7.0> sudo apt-mark hold cleanuparr

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

dnf --showduplicates list cleanuparr sudo dnf downgrade cleanuparr-<VERSION_BEFORE_2.7.0> sudo dnf versionlock add cleanuparr

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.
