500: Internal Service Error

I’m just getting started with Salamander. Followed steps 1-5 from the Server setup page. Whenever I try to open any notebook I get sent to an error page saying “500 : Internal Service Error”. Is there a simple fix for this? Any help would be appreciated.

Never mind. Using the following in the terminal solved the issue:

conda install nbconvert notebook

Ran into this. The fix worked, but can somebody explain why we have to do this?

This did not fix my error

Thanks it worked for me, i had to restart the jupyter server.
Also if you can explain why we have to do this? and where can i get logs when i encounter Internal Server error?

pip install --upgrade nbconvert

This worked for me.
