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 8.1.0.0 (Debian / Ubuntu)

apt-cache madison hcl-devops-deploy sudo apt install hcl-devops-deploy=<VERSION_BEFORE_8.1.0.0> sudo apt-mark hold hcl-devops-deploy

dnf --showduplicates list hcl-devops-deploy sudo dnf downgrade hcl-devops-deploy-<VERSION_BEFORE_8.1.0.0> sudo dnf versionlock add hcl-devops-deploy

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.
