nmark nmcms DOWNGRADE

Affected: 2.1

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.1

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 2.1 (Debian / Ubuntu)

apt-cache madison nmcms sudo apt install nmcms=<VERSION_BEFORE_2.1> sudo apt-mark hold nmcms

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

dnf --showduplicates list nmcms sudo dnf downgrade nmcms-<VERSION_BEFORE_2.1> sudo dnf versionlock add nmcms

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.
