Timeline

wso2 api control plane UPGRADE
Affected: >= 4.5.0 and < 4.5.0.56 · >= 4.6.0 and < 4.6.0.20
Fixed in: 4.5.0.56, 4.6.0.20
Safe to downgrade to: a release before 4.5.0
1. Check installed version
apt-cache policy api-control-plane || rpm -q api-control-plane || api-control-plane --version
2. UPGRADE to 4.5.0.56 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade api-control-plane
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade api-control-plane
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 4.5.0 (Debian / Ubuntu)
apt-cache madison api-control-plane sudo apt install api-control-plane=<VERSION_BEFORE_4.5.0> sudo apt-mark hold api-control-plane
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list api-control-plane sudo dnf downgrade api-control-plane-<VERSION_BEFORE_4.5.0> sudo dnf versionlock add api-control-plane
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.
