Description Miro Hrončok 2026-07-25 09:54:36 UTC

In https://bodhi.fedoraproject.org/updates/FEDORA-2026-2551d0d66b we have shipped Python 3.15.0b4.

All packages that link to libpython or have extension modules should be rebuilt, or they will segfault on import/usage.

Packages using stable ABI might not need a rebuild.

This package was not rebuilt because we were unable to do so.
Please rebuild it with Python 3.15.0b4+ ASAP.

If you are sure this package does not need a rebuild, feel free to close this bugzilla.

Thanks

A build fails with:

This might indicate a dependency needs to be rebuilt with Python 3.15.0b4+ first.

Possibly python-scikit-learn, the only arch-dependent Python package in root.log that was not rebuilt yet with b4. It likely has a stale C extension causing the segfault.
