Except for one I filed earlier, none of them have bugs currently. It's enough I'm not sure if it qualifies as a MBF for not. Here's what I'll file if I get sufficiently motivated and have the time: This package failed a recent autopkgtest and this is one of the blockers for python3-defaults migration. It failed because python3.7 was installed in the chroot and the current autopkgtest doesn't handle that. Autopkgtests should be run for all supported versions. The package attempts to do that, but in a way that is unreliable. Based on a review of the failure log (I have not looked at the package, so there's a small chance the root cause is different), the autopkgtest uses the output of py3versions -i to iterate over available python3 versions. The -i flag indicates all installed versions. In many cases python3.7 is still partially installed, so it is included in the tests, but fails. The reliable way to do this is add python3-all to your tests depends in debian/tests/control and change the py3versions call to py3versions -s. These two steps will ensure all supported python3 interpreters are fully installed and that the tests are run against them. As this is a blocker for getting python3.8 as default python3 into bullseye, please address this soon. I'm open to doing NMUs if anyone would like the support. Please let me know if you would like for me to do that. Scott K dd-list is attached. If any of you fix these before I file the bugs, please let me know so I can skip that package when I do. Scott K
