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 1.17.0 (Debian / Ubuntu)

apt-cache madison performance sudo apt install performance=<VERSION_BEFORE_1.17.0> sudo apt-mark hold performance

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

dnf --showduplicates list performance sudo dnf downgrade performance-<VERSION_BEFORE_1.17.0> sudo dnf versionlock add performance

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.
