Fail deploying metrics-server and prometheus-adapter

[mssokal]

Used the exact same steps and ran into this problem

$ kubectl -n monitoring-system get helmreleases
NAME                 RELEASE      PHASE              STATUS     MESSAGE                                                                            AGE
