Bug#999516: python-ltfatpy: FTBFS with matplotlib 3.5 (in experimental): dh_auto_test: error: pybuild --test --test-pytest -i python{version} -p 3.9 returned exit code 13

[Lucas Nussbaum]

Source: python-ltfatpy
Version: 1.0.16-5
Severity: important
Justification: FTBFS
Tags: bookworm sid ftbfs
User: lucas at debian.org
Usertags: ftbfs-matplotlib35

Hi,

During a rebuild of all packages in sid, your package failed to build
on amd64, using matplotlib 3.5 currently in experimental. This version
will soon be uploaded to unstable.

If you have questions about this, please contact Sandro Tosi
<morph at debian.org>.

Relevant part (hopefully):
