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 2.2.0 (Debian / Ubuntu)

apt-cache madison application-service sudo apt install application-service=<VERSION_BEFORE_2.2.0> sudo apt-mark hold application-service

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

dnf --showduplicates list application-service sudo dnf downgrade application-service-<VERSION_BEFORE_2.2.0> sudo dnf versionlock add application-service

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.
