blender blender UPGRADE

Affected: < 2.83.19 · >= 2.90.0 and < 2.93.8 · >= 3.0 and < 3.1

Fixed in: 2.83.19, 2.93.8, 3.1

Safe to downgrade to: a release before 2.90.0

1. Check installed version

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

2. UPGRADE to 2.83.19 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade blender

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade blender

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 2.90.0 (Debian / Ubuntu)

apt-cache madison blender sudo apt install blender=<VERSION_BEFORE_2.90.0> sudo apt-mark hold blender

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list blender sudo dnf downgrade blender-<VERSION_BEFORE_2.90.0> 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.

debian debian linux MITIGATE

Affected: 9.0 · 10.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 9.0

Check your OS release

cat /etc/os-release; uname -r

Debian / Ubuntu

sudo apt update && sudo apt full-upgrade

RHEL / Amazon Linux / Fedora

sudo dnf upgrade --refresh

Windows

Install the latest cumulative update from Windows Update
