Hi all,
I'm having an issue that I can't seem to find any reference to anywhere
else, but I'm hoping someone has seen it and can help me.
I've set up jupyterhub with the sudospawner according to the instructions
on the wiki, on an ubuntu server. The user logins for this server
(including myself) are actually provided via some directory service voodoo
(active directory maybe?) that our institution sysadmins manage and that I
know nothing about.
With the sudospawner, jupyterhub works fine for me logging in as myself.
My users can also login just fine (that is, they authenticate without
problem), but then they get a 500 Server Error message and it appears their
single user server is not starting up. There's nothing in the jupyterhub
log that seems relevant, but I'll post it below.
In desperation I tried a number of things, and one thing seemed to work:
having a user ssh to the host and launch 'jupyter notebook' once. After
this (after shutting down the notebook server thus created) they were able
to successfully go through jupyterhub. I figured this had something to do
with the files created in .local/share/juptyerhub, so I tried destroying
those files for my own account in hopes of reproducing the problem, but I
can't reproduce - my account stubbornly refuses to not work :) I've not
yet reproduced this solution with another user (hope to try tomorrow, but I
need to resolve this ASAP). So I'm not certain this is the issue (maybe
just a coincidence). Perhaps the issue has something to do with the way
users are managed. If it isn't a coincidence, then I'm hoping someone can
tell me a workaround so all my users (~50 of them) don't have to ssh and
launch jupyter notebook, etc. Some of them will not be comfortable
performing this task! (I cannot do it for them with sudo without violating
the rules of my institution.)
Here's the output of 'jupyter troubleshoot':
