rice open motion planning library DOWNGRADE

Affected: 1.5.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.5.0

1. Check installed version

apt-cache policy open-motion-planning-library || rpm -q open-motion-planning-library || open-motion-planning-library --version

2. No fixed release: DOWNGRADE to a release before 1.5.0 (Debian / Ubuntu)

apt-cache madison open-motion-planning-library sudo apt install open-motion-planning-library=<VERSION_BEFORE_1.5.0> sudo apt-mark hold open-motion-planning-library

dnf --showduplicates list open-motion-planning-library sudo dnf downgrade open-motion-planning-library-<VERSION_BEFORE_1.5.0> sudo dnf versionlock add open-motion-planning-library

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.
