Error when launching a kernel

JupyterHub
1

Hi,

I have installed TLJH on my Ubuntu 20.04 Workstation. The problem I have is that whenever I try to launch a Python notebook, I get a page with “500 : Internal Server Error”. I don’t have this problem when I switch to the jupyterlab interface. Note that I have tried to create other users and they have the same problem.

Note that before installing TLJH, I had already worked with Jupyter coming from Anaconda and I had installed an OCaml kernel which was imported from the very beginning when TLJH was first launched. I removed this kernel as I first thought the problem was coming from this kernel at first,

Where can I look so that I can understand this issue? Any idea?

Best regards,
Francois

Probably the first thing you want to do is look at the logs to see what the underlying error is. That should hopefully point in the direction of a fix.
