Description Fedora Release Engineering 2026-07-21 21:26:15 UTC 
python-tpm2-pytss failed to build from source in Fedora rawhide/f45

https://koji.fedoraproject.org/koji/taskinfo?taskID=147906042


For details on the mass rebuild see:

https://fedoraproject.org/wiki/Fedora_45_Mass_Rebuild
Please fix python-tpm2-pytss 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,
python-tpm2-pytss will be orphaned. Before branching of Fedora 46,
python-tpm2-pytss will be retired, if it still fails to build.

Comment 4 Jakub Jelen 2026-07-27 08:59:13 UTC 
The regexes sounds like fixed with the following three upstream commits, but even with them I am getting some failures:

cd433019cf109986d523ab4dc644af723f6f0d59
dba34b3a0af39122381d613a7beb3a0d46b7ae21

I will try to investigate it further:
