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 7.161.0 (Debian / Ubuntu)

apt-cache madison artifactory sudo apt install artifactory=<VERSION_BEFORE_7.161.0> sudo apt-mark hold artifactory

dnf --showduplicates list artifactory sudo dnf downgrade artifactory-<VERSION_BEFORE_7.161.0> sudo dnf versionlock add artifactory

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.
