Timeline

ibm app connect enterprise UPGRADE
Affected: >= 12.0.1.0 and < 12.0.12.28 · >= 13.0.1.0 and < 13.0.8.0
Fixed in: 12.0.12.28, 13.0.8.0
Safe to downgrade to: a release before 12.0.1.0
1. Check installed version
apt-cache policy app-connect-enterprise || rpm -q app-connect-enterprise || app-connect-enterprise --version
2. UPGRADE to 12.0.12.28 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade app-connect-enterprise
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade app-connect-enterprise
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 12.0.1.0 (Debian / Ubuntu)
apt-cache madison app-connect-enterprise sudo apt install app-connect-enterprise=<VERSION_BEFORE_12.0.1.0> sudo apt-mark hold app-connect-enterprise
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list app-connect-enterprise sudo dnf downgrade app-connect-enterprise-<VERSION_BEFORE_12.0.1.0> sudo dnf versionlock add app-connect-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.
