Everything seems to be working fine, however after invoking the jupyter notebook command:

`[I 14:49:40.813 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation). [C 14:49:40.898 NotebookApp]

To access the notebook, open this file in a browser:
    file:///home/jvg/.local/share/jupyter/runtime/nbserver-103-open.html
Or copy and paste one of these URLs:
