Unknown username "whoopsie" in message bus configuration file (Crouton)
For some time I had this notification "Unknown username 'whoopsie' in message bus configuration file" coming up when I started my Ubuntu-server on my Chromebook via crouton. It seemed not to do anything wrong but hey, I hate to see error messages popping up on the screen and not knowing what it really means.

In my search I've learned that the user 'whoopsie'  is being used for the error reporting daemon in Ubuntu.

What worked for me to stop the Error message? 

I didn't have a need for the whoopsie service on my development system,
so I wanted to make sure it was not installed anymore.

sudo apt-get purge whoopsie libwhoopsie0


Finding the config file where the whoopsie reference came from:

cd /etc/dbus-1/system.d
find . | xargs grep 'whoopsie'

in my case that gave the result:

./org.freedesktop.NetworkManager.conf

Edit this file: (sudo nano)

/etc/dbus-1/system.d/org.freedesktop.NetworkManager.conf

Delete the policy section for user 'whoopsie' and save.

That should do it.

Please, there are secret gists, so it doesn't go indexed in google. Thanks!
