Fixed in: no fixed release known

Safe to downgrade to: a release before 7.x-1.0

1. Check installed version

apt-cache policy values || rpm -q values || values --version

2. No fixed release: DOWNGRADE to a release before 7.x-1.0 (Debian / Ubuntu)

apt-cache madison values sudo apt install values=<VERSION_BEFORE_7.x-1.0> sudo apt-mark hold values

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list values sudo dnf downgrade values-<VERSION_BEFORE_7.x-1.0> sudo dnf versionlock add values

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.
