blender blender DOWNGRADE

Affected: 3.3.0 alpha

Fixed in: no fixed release known

Safe to downgrade to: a release before 3.3.0

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 3.3.0 (Debian / Ubuntu)

apt-cache madison blender sudo apt install blender=<VERSION_BEFORE_3.3.0> sudo apt-mark hold blender

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

dnf --showduplicates list blender sudo dnf downgrade blender-<VERSION_BEFORE_3.3.0> sudo dnf versionlock add blender

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.
