Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

apt-cache madison patchwork sudo apt install patchwork=<VERSION_BEFORE_1.1> sudo apt-mark hold patchwork

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

dnf --showduplicates list patchwork sudo dnf downgrade patchwork-<VERSION_BEFORE_1.1> sudo dnf versionlock add patchwork

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.
