    1. Follow https://docs.openshift.com/container-platform/4.12/security/container_security/security-container-signature.html#containers-signature-verify-enable_security-container-signature to enable Signature Verification on cluster master and worker nodes.
    2. "oc describe pod <$redhat-marketplace-pod>" or "oc get events -n openshift-marketplace" to view the errors.
