gog galaxy UPGRADE

Affected: >= 2.0.46 and <= 2.0.51

Fixed in: newer than 2.0.51

Safe to downgrade to: a release before 2.0.46

1. Check installed version

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

2. UPGRADE to newer than 2.0.51 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade galaxy

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 2.0.46 (Debian / Ubuntu)

apt-cache madison galaxy sudo apt install galaxy=<VERSION_BEFORE_2.0.46> sudo apt-mark hold galaxy

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

dnf --showduplicates list galaxy sudo dnf downgrade galaxy-<VERSION_BEFORE_2.0.46> sudo dnf versionlock add galaxy

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.
