Background: almost all components we use are from github.com/red-hat-data-services group, except kf-notebook-controller and odh-notebook-controoler.

from the description we set in the cppas-producs/rhods. it states it is from 

See https://github.com/red-hat-data-services/kubeflow/tree/master/components/notebook-controller

but from the upstream_sources.yaml we can see , it is 
 

   url: https://github.com/opendatahub-io/kubeflow     
   branch: v1.6-branch 

A quick check, that we do not have v1.6-branch exist in "red-hat-data-services/kubeflow" repo

So this is more than just update the upstream_sources.yaml file but need to ensure the branch we try to use exist or if it is the correct one to use.

Action: update from "odh" to "rhods" in Github with url and/or branch if needed
