Description Karolina Surma 2025-05-14 08:52:51 UTC

python-aioesphomeapi fails to build with Python 3.14.0b1.

The error comes from protobuf which doesn't work with Python 3.14 - it's reported in https://bugzilla.redhat.com/show_bug.cgi?id=2343969 but as we approach mass rebuild, I decided to raise this also with some of the dependent packages to increase visibility of the issue.

For the build logs, see:
https://copr-be.cloud.fedoraproject.org/results/@python/python3.14-b1/fedora-rawhide-x86_64/09033221-python-aioesphomeapi/

For all our attempts to build python-aioesphomeapi with Python 3.14, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.14-b1/package/python-aioesphomeapi/

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 3.14:
https://copr.fedorainfracloud.org/coprs/g/python/python3.14-b1/

Let us know here if you have any questions.

Python 3.14 is planned to be included in Fedora 43.
To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.14.
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.
