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

2. UPGRADE to 3.3.17 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade grails

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 4.0.0 (Debian / Ubuntu)

apt-cache madison grails sudo apt install grails=<VERSION_BEFORE_4.0.0> sudo apt-mark hold grails

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

dnf --showduplicates list grails sudo dnf downgrade grails-<VERSION_BEFORE_4.0.0> sudo dnf versionlock add grails

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.
