Public bug reported:

If a user is added with '--extrausers' (which happens on ubuntu core)
then adding ssh keys or reporting which keys are added will fail as the users cannot be found.
This seems a general issue as extrausers, see bug 1679765.


The stack trace looks like:

2017-04-04 16:57:00,117 - util.py[WARNING]: Applying ssh credentials failed!
2017-04-04 16:57:00,117 - util.py[DEBUG]: Applying ssh credentials failed!
