godotengine godot UPGRADE

Affected: < 2.1.5 · >= 3.0.0 and < 3.0.6

Fixed in: 2.1.5, 3.0.6

Safe to downgrade to: a release before 3.0.0

1. Check installed version

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

2. UPGRADE to 2.1.5 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade godot

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 3.0.0 (Debian / Ubuntu)

apt-cache madison godot sudo apt install godot=<VERSION_BEFORE_3.0.0> sudo apt-mark hold godot

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

dnf --showduplicates list godot sudo dnf downgrade godot-<VERSION_BEFORE_3.0.0> sudo dnf versionlock add godot

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.
