We thought the latest image would be happy based on updates that
tristanC made. Unfortunately ssh complains with:
2021-12-06 18:33:14.616 [ThreadId 19]: [ERROR] ssh process exited: 255
2021-12-06 18:33:15.618 [ThreadId 19]: Connecting to review.opendev.org:29418
No user exists for uid 11000
Undo only the uid:gid settings as the new image seems to work otherwise.
