alex dunaevsky convex 3d DOWNGRADE

Affected: 0.8_pre1

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.8_pre1

1. Check installed version

apt-cache policy convex-3d || rpm -q convex-3d || convex-3d --version

2. No fixed release: DOWNGRADE to a release before 0.8_pre1 (Debian / Ubuntu)

apt-cache madison convex-3d sudo apt install convex-3d=<VERSION_BEFORE_0.8_pre1> sudo apt-mark hold convex-3d

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

dnf --showduplicates list convex-3d sudo dnf downgrade convex-3d-<VERSION_BEFORE_0.8_pre1> sudo dnf versionlock add convex-3d

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.
