Dear Kouhei Maeda, one of my packages, libervia-backend resp. salutatoi, depends on shortuuid and due to bug #1002445 of 2021-12-22 in shortuuid it will be removed from testing soon.
If you don't have the time to fix the bug right now, I could make an NMU (non-maintainer upload), but I wonder, if it would be better to move the package to the "Debian Python Team"? That would allow many people to make changes, whenever necessary. You would remain in charge of the package, of course. Please, if you don't mind, just send me a short note "go ahead", and I would move the package to the team, fix the bug and update it! Many thanks in advance! Cheers, Martin
