Testing with some other process holding the APT lock:

$ kubectl get nodes/ubuntu-xenial -o json | jq '.status.conditions[] | select(.type == "HostUpgrades")'
{
  "lastHeartbeatTime": "2018-05-23T13:54:02Z",
  "lastTransitionTime": "2018-05-23T13:54:02Z",
  "message": "exec host-upgrades([/usr/bin/unattended-upgrade -v]): Job failed",
  "reason": "HostUpgradeError",
  "status": "False",
  "type": "HostUpgrades"
}
