New releases of this package are available on pypi: https://pypi.org/project/importlib-metadata/#history I've added a mapping for it to anitya, it wasn't linked to a fedora package before: https://release-monitoring.org/project/50323/ I would need importlib-metadata 1.1.3+ on fedora 31 for a poetry update (1.0.0 → 1.0.2).
Mot sure if anitya works on packages retired on rawhide. Anyway, I can look into this later, but you can always send a PR to make it faster. Just make sure tox, pytest, pluggy still work.
Oh, right, it's obsoleted by python 3.8. I'll send you a PR after doing the work.
Alright, this is not so easy as I thought. tox 3.13.2 restricts its importlib-metadata dependency to "< 1". tox 3.14.3 allows ">= 0.12; < 2". Though I'm not sure if updating tox in stable fedora is a good idea. I'll try to update poetry by ignoring the dependency restrictions instead ...
So, updating poetry by relaxing its dependencies seems to work, even without importlib-metadata > 1.1.3. And it's certainly easier than updating all the other packages :)
Fedora 31 is stable at this point; we're not planning to update to the new version.
