gradle enterprise UPGRADE

Affected: >= 2018.5 and <= 2020.2.4

Fixed in: newer than 2020.2.4

Safe to downgrade to: a release before 2018.5

1. Check installed version

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

2. UPGRADE to newer than 2020.2.4 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade enterprise

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 2018.5 (Debian / Ubuntu)

apt-cache madison enterprise sudo apt install enterprise=<VERSION_BEFORE_2018.5> sudo apt-mark hold enterprise

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

dnf --showduplicates list enterprise sudo dnf downgrade enterprise-<VERSION_BEFORE_2018.5> sudo dnf versionlock add enterprise

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.
