ModuleNotFoundError: No module named 'setuptools_scm.file_finder_git'

I'm stumped by this one. Setuptools, pip, and all of the other build-fu are built as SPKGs.

AttributeError: type object 'Axis' has no attribute '_set_ticklabels'

That was an internal method and was refactored in matplotlib/matplotlib#24577

Whatever package is trying to use it probably needs its lower bound increased, but it's not obvious from the CI logs which package that is.

[dimpase]

fedora 33 and 34 are not relevant here.

their python stacks are way too old

[mkoeppe]

it's exactly the purpose of configure to reject versions that are too old

[dimpase]

it'd become a very hard task to maintain such a setup, if we going to lower-bound versions of every last package we have.

Time for modularisation, in particular everything jupyter (which is the largest pile of packages we have) ought to be something you can plug in seamlessly. It's really not Sage's task to maintain our own working jupyter setup, with all the needed versions etc.

E.g. a project like scipy, which has funding, full-time people on payroll etc., and narrower in scope than Sage, doesn't try to do this.

[dimpase]

as found out today, Fedora 38 carries ipython 8.9, which does not have the sphinxext component.

So we need a test for this component, not just a version check.

Maybe the corresponding autoconf macro should take an extra parameter for such a case.

The macro probably ought to be refactored so that a testing venv is created only once, to speed it up.
Not urgent, but would be nice.
