Notebook building fail 24 March 2022

[fangohr]

We have a new error: https://github.com/oscovida/oscovida.github.io/runs/5688255990?check_suite_focus=true#step:6:281

As we have not changed anything, I guess this comes from changing behaviour of dependencies which we do not pin.

I suggest we pick up @kirienko 's proposal of pinning all versions (once we have this working again).

This page shows which runs completed and which failed: https://github.com/oscovida/oscovida.github.io/actions

Seems to be an indirect dependency problem.
So the actual problem is in jinja2 due to the update to 3.1.0. Namely, they say that Markup and escape should be imported from MarkupSafe. But I don't see the place where we import jinja2 explicitly.

[kirienko]

Aha! That's nbconvert again!

[kirienko]

Okay, the problem is that nbconvert still uses the old import.
Here is an open issue: jupyter/nbconvert#1737
When it is solved, I think our issue will be gone too. There is a pull request made but I don't know how fast it will propagate. But on the other hand, untangling this dependency knot manually might be painful and will end up with a fragile solution.

Issue was closed by accident.

I have fixed the Jinja2 version in both environments (i.e. for oscovida itself, defined in setup.py, and for the requirements for the vent for pelican (requirements_pelican.txt ).

All the tests pass then. I have merged, and am waiting for the outcome of the webpage regeneration attempt.https://github.com/oscovida/oscovida.github.io/actions/runs/2043845872
