Description Fedora Release Engineering 2026-07-21 20:15:16 UTC 
libsonata failed to build from source in Fedora rawhide/f45

https://koji.fedoraproject.org/koji/taskinfo?taskID=147870935


For details on the mass rebuild see:

https://fedoraproject.org/wiki/Fedora_45_Mass_Rebuild
Please fix libsonata at your earliest convenience and set the bug's status to
ASSIGNED when you start fixing it. If the bug remains in NEW state for 8 weeks,
libsonata will be orphaned. Before branching of Fedora 46,
libsonata will be retired, if it still fails to build.

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. Thanks

Thanks---this one is on the (long) list of FTBFS packages we're working on.
Comment 6 Miro Hrončok 2026-09-30 08:11:45 UTC 
This is a reminder that Fedora 45 final freeze starts next week and we really need to either rebuild python3-libsonata or at least thoroughly test it to see if it works correctly without the rebuild.
Comment 7 Miro Hrončok 2026-09-30 08:59:10 UTC 
$ python3
Python 3.15.0rc2 (3.15.0~rc2-1.fc45.x86_64, Sep  3 2026, 00:00:00) [GCC 16.2.1 20260819 (Red Hat 16.2.1-2)] on linux

Comment 8 Ankur Sinha (FranciscoD) 2026-09-30 09:15:16 UTC 
Should be fixed this week. Actively being worked upon.
