apache linkis UPGRADE

Affected: >= 1.3.0 and < 1.6.0

Fixed in: 1.6.0

Safe to downgrade to: a release before 1.3.0

1. Check installed version

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

2. UPGRADE to 1.6.0 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade linkis

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 1.3.0 (Debian / Ubuntu)

apt-cache madison linkis sudo apt install linkis=<VERSION_BEFORE_1.3.0> sudo apt-mark hold linkis

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

dnf --showduplicates list linkis sudo dnf downgrade linkis-<VERSION_BEFORE_1.3.0> sudo dnf versionlock add linkis

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.
