Hi,

I'm trying to update @world, but I'm hitting a conflict that I do not understand.

Before coming here, I tried to create a thread on the forums, but the forums are totally broken :
> General Error - Error in posting
(Please upgrade the forums - https://bugs.gentoo.org/880071)

I'm on stable amd64, and do no have any special configuration regarding python.

emerge absolutely wants to keep python3_12 on dev-python/trove-classifiers, I don't see why :
> # emerge -avuDU @world

> >=dev-python/trove-classifiers-2025.4.11.15 python_targets_python3_12

If I try to rebuild =dev-python/setuptools-78.1.0 package, emerge fails with a slot conflict (see setuptools-78.1.0.txt).
If I ask emerge to rebuild dev-python/setuptools without any version, emerge wants to update the package to latest ~amd64 (see setuptools.txt)

If anyone has an explanation. Thanks.

Explanation given by grknight on the forums¹ :

> It is dev-build/scons holding up the upgrade as it should be rebuilt but isn't.
> This is cascaded from net-libs/serf which isn't marked ready² for python 3.13 (oh joy python-any-r1 problems again!).

Thank you, closing.
