-Pods in ImagePullBackOff State
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-If the pods are stuck in ImagePullBackOff state, then it's likely an issue with credentials.  To verify this,
-run *kubectl describe* on a pod in that state, for example::
-
-    kubectl -n omec describe pod gnbsim-0
-
-Look in the *Events* section for more information about why the image pull failed.  If you see *unauthorized to
-access repository* then it's probably a credentials issue; see `Set up Authentication Tokens`_ above.

 4G Test Fails
 ^^^^^^^^^^^^^
 Occasionally *make test* (for 4G) fails for unknown reasons; this is true regardless of which Helm charts are used.
