ibm application gateway UPGRADE

Affected: >= 19.12 and <= 24.09

Fixed in: newer than 24.09

Safe to downgrade to: a release before 19.12

1. Check installed version

apt-cache policy application-gateway || rpm -q application-gateway || application-gateway --version

2. UPGRADE to newer than 24.09 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade application-gateway

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade application-gateway

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 19.12 (Debian / Ubuntu)

apt-cache madison application-gateway sudo apt install application-gateway=<VERSION_BEFORE_19.12> sudo apt-mark hold application-gateway

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

dnf --showduplicates list application-gateway sudo dnf downgrade application-gateway-<VERSION_BEFORE_19.12> sudo dnf versionlock add application-gateway

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.
