wso2 api manager UPGRADE
Affected: >= 3.2.0 and < 3.2.0.408 · >= 3.2.1 and < 3.2.1.32 · >= 4.0.0 and < 4.0.0.293 · >= 4.1.0 and < 4.1.0.187
Fixed in: 3.2.0.408, 3.2.1.32, 4.0.0.293, 4.1.0.187
Safe to downgrade to: a release before 3.2.0
1. Check installed version
apt-cache policy api-manager || rpm -q api-manager || api-manager --version
2. UPGRADE to 3.2.0.408 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade api-manager
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade api-manager
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 3.2.0 (Debian / Ubuntu)
apt-cache madison api-manager sudo apt install api-manager=<VERSION_BEFORE_3.2.0> sudo apt-mark hold api-manager
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list api-manager sudo dnf downgrade api-manager-<VERSION_BEFORE_3.2.0> sudo dnf versionlock add api-manager
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.
