Fix: https://salsa.debian.org/freedombox-team/freedombox/-/commit/23e760c9a0f85fa4973a01d827f983e06411c2f1

[Andreas Hasenack (ahasenack)]

Hm, that's not it.

[Andreas Hasenack (ahasenack)]

/usr/lib/python3/dist-packages/bootstrapform/meta.py comes from src:python-django-bootstrap-form, changing package

[Andreas Hasenack (ahasenack)]

Testing a patch. I'm working on this because it came up in the samba migration in noble (freedombox, a reverse DEP8 dependency, started failing).

[Andreas Hasenack (ahasenack)]

I fixed the StrictVersion import, but the tests are failing[1] with python 3.12 even without my patch due to something else.

Just in case the DEP8 log gets wiped, this is the error:

So I thought, and verified it locally, that the problem was that the test ran with an unpatched test suite. The package has a patch for django 4 which also touches the tests. If I run the tests in an unpatched source, I get the same failure.

So I added the "build-needed" restriction to the test in d/t/control, and great, test passed locally. Uploaded to PPA, and it didn't. My last attempt was to verify that the runtests.py file that the DEP8 test was about to run was indeed the patched one, and it was.

¯\_(ツ)_/¯

Time to sleep on it.

This seems fixed via https://launchpad.net/ubuntu/+source/python-django-bootstrap-form/3.4-8
