godotsteam godotsteam UPGRADE

Affected: >= 4.17.0 and <= 4.23.2

Fixed in: newer than 4.23.2

Safe to downgrade to: a release before 4.17.0

1. Check installed version

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

2. UPGRADE to newer than 4.23.2 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

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 4.17.0 (Debian / Ubuntu)

apt-cache madison godotsteam sudo apt install godotsteam=<VERSION_BEFORE_4.17.0> sudo apt-mark hold godotsteam

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

dnf --showduplicates list godotsteam sudo dnf downgrade godotsteam-<VERSION_BEFORE_4.17.0> sudo dnf versionlock add godotsteam

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.
