I have the same issue. This worked fine on my Mac but when I moved to Ubuntu I get the timeout error.
One thing I noticed was the bash location was different, so I updated that but it did not fix the problem.

Is there any way we can see what is causing the spawner to hang?

I fixed this problem with:
jupyterhub/jupyterhub#1467 (comment)

make sue you are running as user ubuntu.
