Hello,
I am having an odd problem with jupyterhub on two ubuntu machines where I
just installed jupyterhub - one is Ubuntu 16.04, one is ubuntu 16.10.
Jupyterhub version is 0.7.0. Python version is the default 3.5 for each of
the OSes.
I get the following errors:

Does this sound familiar to anyone? Any idea if there is something I might
have configured wrong to make this happen? If I can provide more
information that might be useful, please let me know.
I tried deleting the jupyterhub.sqlite database file, and it has no
effect. I always get this same set of errors with the same set of users.
It is very strange. I've been using jupyterhub for a few years now, have
never seen anything like this.
Any help will be greatly appreciated.
Thanks,
Jonathan Morgan
