I know you wrote this as well, but just for the record I tried dropping
jinja2 from this list and it still pulled it in automatically:

Collecting Jinja2>=3.0

Tried with a few different versions:

$ (. sphinx-2.4.4/bin/activate && scripts/sphinx-pre-install)
Detected OS: Ubuntu 22.04.3 LTS.
Sphinx version: 2.4.4


You may also use the newer Sphinx version 7.2.6 with:
         . /home/vegard/linux/sphinx_latest/bin/activate
[...]

$ (. sphinx-2.0/bin/activate && scripts/sphinx-pre-install)
ERROR: Sphinx version is 2.0.0. It should be >= 2.4.4
Detected OS: Ubuntu 22.04.3 LTS.
Sphinx version: 2.0.0


Need to activate Sphinx (version 7.2.6) on virtualenv with:
         . /home/vegard/linux/sphinx_latest/bin/activate
[...]

$ scripts/sphinx-pre-install
Detected OS: Ubuntu 22.04.3 LTS.
Sphinx version: 4.3.2


All optional dependencies are met.
Needed package dependencies are met.


One remark I have is that it didn't encourage me to upgrade to 7.2.6 in
the last one (using the system Sphinx 4.3.2) although it did for the
2.4.4 virtualenv. Maybe that's expected. I didn't look into it. Anyway,
FWIW:
