apache dolphinscheduler UPGRADE

Affected: >= 3.2.0 and < 3.3.1

Fixed in: 3.3.1

Safe to downgrade to: a release before 3.2.0

1. Check installed version

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

2. UPGRADE to 3.3.1 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade dolphinscheduler

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 3.2.0 (Debian / Ubuntu)

apt-cache madison dolphinscheduler sudo apt install dolphinscheduler=<VERSION_BEFORE_3.2.0> sudo apt-mark hold dolphinscheduler

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

dnf --showduplicates list dolphinscheduler sudo dnf downgrade dolphinscheduler-<VERSION_BEFORE_3.2.0> sudo dnf versionlock add dolphinscheduler

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.
