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 7.117.0 (Debian / Ubuntu)
apt-cache madison artifactory
sudo apt install artifactory=<VERSION_BEFORE_7.117.0>
sudo apt-mark hold artifactory
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list artifactory
sudo dnf downgrade artifactory-<VERSION_BEFORE_7.117.0>
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.
