gradle enterprise DOWNGRADE

Affected: 2018.5

Fixed in: no fixed release known

Safe to downgrade to: a release before 2018.5

1. Check installed version

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

2. No fixed release: 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

2. No fixed release: 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.
