ibm websphere application server UPGRADE
Affected: >= 17.0.0.3 and < 26.0.0.9
Fixed in: 26.0.0.9
Safe to downgrade to: a release before 17.0.0.3
1. Check installed version
apt-cache policy websphere-application-server || rpm -q websphere-application-server || websphere-application-server --version
2. UPGRADE to 26.0.0.9 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade websphere-application-server
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade websphere-application-server
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 17.0.0.3 (Debian / Ubuntu)
apt-cache madison websphere-application-server
sudo apt install websphere-application-server=<VERSION_BEFORE_17.0.0.3>
sudo apt-mark hold websphere-application-server
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list websphere-application-server
sudo dnf downgrade websphere-application-server-<VERSION_BEFORE_17.0.0.3>
sudo dnf versionlock add websphere-application-server
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.
