Downgrading packaging to 22.O (which portage then further downgraded to 21.3) fixes the issue.

Reproducible: Always

Wondering if this is actually pbr or another package that gets imported.

[Comment 2 Rémi Cardona 2023-02-03 07:15:32 UTC]

Hard to say, as apparently pbr's main purpose is to monkey patch setuptools and provide extensions for it... So this might be quite the rabbit hole.

No bug on the upstream bug tracker (launchpad... so I may have missed something) that I could find.

> *   dev-python/setuptools         : 65.6.3

Here's your culprit.  <67 requires <packaging-22, and 65.7.0 (which is the oldest version in ::gentoo) has a correct dep.

[Comment 4 Rémi Cardona 2023-02-03 14:52:41 UTC]

I was simply doing:

# emerge -DuN @world --changed-deps -av --keep-going

like I always do and hit this. So there's a missing/bad dep somewhere?

[Comment 5 Sam James 2023-02-03 14:59:41 UTC]

Yes, Portage doesn't aggressively update deps-of-deps *in order* unless there's a constraint somewhere that forces it (which is correct, really).

So we need to find somewhere to jam one in, I guess. Simply not having bad versions in tree anymore isn't sufficient.
