Affected: >= 0.5.0 and < 2.2.0

Fixed in: 2.2.0

Safe to downgrade to: a release before 0.5.0

1. Check installed version

apt-cache policy connector-for-cc++ || rpm -q connector-for-cc++ || connector-for-cc++ --version

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 0.5.0 (Debian / Ubuntu)

apt-cache madison connector-for-cc++ sudo apt install connector-for-cc++=<VERSION_BEFORE_0.5.0> sudo apt-mark hold connector-for-cc++

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

dnf --showduplicates list connector-for-cc++ sudo dnf downgrade connector-for-cc++-<VERSION_BEFORE_0.5.0> sudo dnf versionlock add connector-for-cc++

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.
