Safe to downgrade to: a release before 4.0

1. Check installed version

apt-cache policy wms || rpm -q wms || wms --version

2. UPGRADE to 4.04.45396.23 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade wms

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade wms

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 4.0 (Debian / Ubuntu)

apt-cache madison wms sudo apt install wms=<VERSION_BEFORE_4.0> sudo apt-mark hold wms

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

dnf --showduplicates list wms sudo dnf downgrade wms-<VERSION_BEFORE_4.0> sudo dnf versionlock add wms

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.
