integrated computer solutions openmotif DOWNGRADE

Affected: 2.2.3

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.2.3

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 2.2.3 (Debian / Ubuntu)

apt-cache madison openmotif sudo apt install openmotif=<VERSION_BEFORE_2.2.3> sudo apt-mark hold openmotif

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

dnf --showduplicates list openmotif sudo dnf downgrade openmotif-<VERSION_BEFORE_2.2.3> sudo dnf versionlock add openmotif

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.
