  Reason: ClusterOperatorsNotUpgradeable
  Message: Multiple cluster operators should not be upgraded between minor versions:
  * Cluster operator machine-config should not be upgraded between minor versions: PoolUpdating: One or more machine config pools are updating, please see `oc get mcp` for further details
  * Cluster operator operator-lifecycle-manager should not be upgraded between minor versions: IncompatibleOperatorsInstalled: ClusterServiceVersions blocking cluster upgrade: service-telemetry/smart-gateway-operator.v5.0.1743671602 is incompatible with OpenShift minor versions greater than 4.16,service-telemetry/service-telemetry-operator.v1.5.1743671601 is incompatible with OpenShift minor versions greater than 4.16,openshift-logging/cluster-logging.v5.9.15 is incompatible with OpenShift minor versions greater than 4.16

Upstream is unset, so the cluster will use an appropriate default.
