ibm engineering ai hub UPGRADE

Affected: >= 1.0.0 and < 1.3.0

Fixed in: 1.3.0

Safe to downgrade to: a release before 1.0.0

1. Check installed version

apt-cache policy engineering-ai-hub || rpm -q engineering-ai-hub || engineering-ai-hub --version

2. UPGRADE to 1.3.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade engineering-ai-hub

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade engineering-ai-hub

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 1.0.0 (Debian / Ubuntu)

apt-cache madison engineering-ai-hub sudo apt install engineering-ai-hub=<VERSION_BEFORE_1.0.0> sudo apt-mark hold engineering-ai-hub

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

dnf --showduplicates list engineering-ai-hub sudo dnf downgrade engineering-ai-hub-<VERSION_BEFORE_1.0.0> sudo dnf versionlock add engineering-ai-hub

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.
