localization manager project localization manager UPGRADE

Affected: < 7.4.0 · >= 8.0.0 and < 8.7.0 · >= 9.0.0 and < 9.2.0

Fixed in: 7.4.0, 8.7.0, 9.2.0

Safe to downgrade to: a release before 8.0.0

1. Check installed version

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

2. UPGRADE to 7.4.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade localization-manager

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade localization-manager

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 localization-manager sudo apt install localization-manager=<VERSION_BEFORE_8.0.0> sudo apt-mark hold localization-manager

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

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