ibm api connect UPGRADE

Affected: >= 12.1.0.0 and < 12.1.1.0

Fixed in: 12.1.1.0

Safe to downgrade to: a release before 12.1.0.0

1. Check installed version

apt-cache policy api-connect || rpm -q api-connect || api-connect --version

2. UPGRADE to 12.1.1.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade api-connect

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade api-connect

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 12.1.0.0 (Debian / Ubuntu)

apt-cache madison api-connect sudo apt install api-connect=<VERSION_BEFORE_12.1.0.0> sudo apt-mark hold api-connect

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

dnf --showduplicates list api-connect sudo dnf downgrade api-connect-<VERSION_BEFORE_12.1.0.0> sudo dnf versionlock add api-connect

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.
