Fixed in: no fixed release known

Safe to downgrade to: a release before 0.8

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 0.8 (Debian / Ubuntu)

apt-cache madison cacti sudo apt install cacti=<VERSION_BEFORE_0.8> sudo apt-mark hold cacti

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

dnf --showduplicates list cacti sudo dnf downgrade cacti-<VERSION_BEFORE_0.8> sudo dnf versionlock add cacti

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.
