Reproducible: Always
Comment 1 Miro Hrončok 2026-06-07 06:45:41 UTC 
Note that this error is notcritical, only anoying. See https://github.com/python/cpython/issues/149671

Also, it needs to be fixed in packages owning /usr/lib/python3.15/site-packages/straight.plugin-1.5.0-py3.15-nspkg and /usr/lib/python3.15/site-packages/Paste-3.10.1-py3.15-nspkg.pth:

Comment 3 Miro Hrončok 2026-06-19 08:59:12 UTC 
Please test with python3.15-3.15.0~b2-5.fc45 -- should be fixed now.
Comment 4 Kevin Fenzi 2026-06-23 01:16:22 UTC 
Yes, seems to be. Thanks!
