lepton-cms leptoncms DOWNGRADE

Affected: 7.1.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 7.1.0

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 7.1.0 (Debian / Ubuntu)

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

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

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

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.
