3. If no update is available yet, DOWNGRADE to a release before 12.0.1.0 (Debian / Ubuntu)
apt-cache madison app-connect-enterprise
sudo apt install app-connect-enterprise=<VERSION_BEFORE_12.0.1.0>
sudo apt-mark hold app-connect-enterprise

dnf --showduplicates list app-connect-enterprise
sudo dnf downgrade app-connect-enterprise-<VERSION_BEFORE_12.0.1.0>
sudo dnf versionlock add app-connect-enterprise
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.
