oxygenz clipbucket UPGRADE

Affected: >= 5.3 and < 5.5.2-157

Fixed in: 5.5.2-157

Safe to downgrade to: a release before 5.3

1. Check installed version

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

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 5.3 (Debian / Ubuntu)

apt-cache madison clipbucket sudo apt install clipbucket=<VERSION_BEFORE_5.3> sudo apt-mark hold clipbucket

dnf --showduplicates list clipbucket sudo dnf downgrade clipbucket-<VERSION_BEFORE_5.3> sudo dnf versionlock add clipbucket

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.
