ibm application gateway operator UPGRADE
Affected: >= 22.2.0 and <= 26.6.0
Fixed in: newer than 26.6.0
Safe to downgrade to: a release before 22.2.0
1. Check installed version
apt-cache policy application-gateway-operator || rpm -q application-gateway-operator || application-gateway-operator --version
2. UPGRADE to newer than 26.6.0 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade application-gateway-operator
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade application-gateway-operator
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 22.2.0 (Debian / Ubuntu)
apt-cache madison application-gateway-operator
sudo apt install application-gateway-operator=<VERSION_BEFORE_22.2.0>
sudo apt-mark hold application-gateway-operator
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list application-gateway-operator
sudo dnf downgrade application-gateway-operator-<VERSION_BEFORE_22.2.0>
sudo dnf versionlock add application-gateway-operator
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.
