This is failing possibly due to a glibc update from 2.40 to 2.41, it's unrelated to Python3.14. On Fedora < 42: from socket import getfqdn getfqdn() 'localhost.localdomain' Which will get resolved usually in 127.0.0.1 e.g. with socket.gethostbyname(getfqdn()) But on Fedora >= 42 getfqdn() '3f93fd8e1d304e40ba598b3f15c41c11' Which obviously cannot get resolved, hence the test fails at "socket.gethostbyname(getfqdn())" with "socket.gaierror: [Errno -3] Temporary failure in name resolution" This could also be due to mock assigning the hostname to the image ID instead of the previous default. Not sure where the change was implemented but basically we'll have to just fallback to 127.0.0.1 if getfqdn() fails. Upstream is abandoned. I'll prepare a patch. The issue here is that systemd has been removed from the dependency chain (or the buildroot or something) from F42 and onwoards, hence it doesn't create a hostname.

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.
