For the build logs, see:
https://copr-be.cloud.fedoraproject.org/results/@python/python3.13/fedora...

For all our attempts to build python-cloudpickle with Python 3.13, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.13/package/pytho...

Testing and mass rebuild of packages is happening in copr.
You can follow these instructions to test locally in mock if your package
builds with Python 3.13:
https://copr.fedorainfracloud.org/coprs/g/python/python3.13/

Let us know here if you have any questions.

Python 3.13 is planned to be included in Fedora 41.
To make that update smoother, we're building Fedora packages with all
pre-releases of Python 3.13.
A build failure prevents us from testing all dependent packages (transitive
[Build]Requires),
so if this package is required a lot, it's important for us to get it fixed
soon.

We'd appreciate help from the people who know this package best,
but if you don't want to work on this now, let us know so we can try to work
around it on our side.
