[Pkg-mozext-maintainers] Bug#937085: Bug#937085: mozilla-devscripts: Python2 removal in sid/bullseye

[Jann Haber]

Hi all,

I just updated the MR on Salsa for redland-bindings, it now successfully creates a python3-librdf package instead of the python-librdf package. This change still needs to be tested, however it looks good, since the build process runs without obvious errors. The upload to unstable I assume needs to be done together with mozilla-devscripts, once it is also converted to python3.
Benjamin, you have done some work on mozilla-devscripts and got stuck since redland-bindings were python2 only. Can you provide any insight on how to test the new package properly? What would be the next steps for mozilla-devscripts?

Best Regards,
Jann
