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 3.0.14989 (Debian / Ubuntu)
apt-cache madison ur-software sudo apt install ur-software=<VERSION_BEFORE_3.0.14989> sudo apt-mark hold ur-software
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list ur-software sudo dnf downgrade ur-software-<VERSION_BEFORE_3.0.14989> sudo dnf versionlock add ur-software
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.
