Ralf,
Thanks for this. I tried your installation procedure on my "Linux Mint
19.3 Tricia base: Ubuntu 18.04 bionic" system and everything seemed
to work fine except the installation of JupyText.
After performing the steps in
* (optional) Install JupyText
when I run
jfricas $FDIR/foo.input
or even just
jfricas
I get the error message:
[C 12:38:09.008 NotebookApp] Bad config encountered during initialization:
[C 12:38:09.008 NotebookApp] The 'contents_manager_class' trait of
<notebook.notebookapp.NotebookApp object at 0x7fa3b6333860> instance
must be a type, but 'jupytext.TextFileContentsManager' could not be
imported
When I checked the config file:
xed $HOME/.jupyter/jupyter_notebook_config.py
I noticed that the installation command
--
3. Make Jupytext available.
sed -i 's|^# *c.NotebookApp.contents_manager_class
=.*|c.NotebookApp.contents_manager_class =
"jupytext.TextFileContentsManager"|;s|^#

--
failed to add the line
c.NotebookApp.use_redirect_file = False
presumably because the file did not previously contain any line like
# *c.NotebookApp.use_redirect_file = .*
Oh... in your case jupyter_notebook_config.py was probably existing.
However, this redirect line was for me only necessary in Ubuntu 22.04.
There when starting "jupyter notebook", firefox would open with a
file://... URL and it would not redirect to the localhost URL where
Jupyter is running.
The actual problem is the jupytext line. What happened to
c.NotebookApp.contents_manager_class in your case? Obviously it points
to jupytext. But then I can only guess that jupytext was not installed
in the virtualenv ($HOME/fricas/venv).
