Hi all,
I'm getting an error running JupyterHub. Right now all I'm doing is
attempting to run it as root with no command-line options.
A couple of weeks ago I was trying to set it up and while I was running
into issues, I wasn't getting this particular problem - I was able to at
least run the command. I'm not sure if something has changed in Jupyter.
Entirely possible that I made a mistake in my setup this time!
Any advice would be appreciated in interpreting the below errors.
Thanks,
Clare
Below is the output of `jupyterhub --debug`:
