Description Petr Pisar 2025-06-11 07:43:34 UTC

A new Python 3.14 (python3-3.14.0~b2-3.fc43.x86_64) just landed into Fedora 43 but tmt was not rebuilt against it. As a result, tmt-1.50.0-1.fc43.noarch cannot be installed:

# LC_ALL=en_US dnf -q install tmt
Failed to resolve the transaction:
Problem: conflicting requests
  - nothing provides python(abi) = 3.13 needed by tmt-1.50.0-1.fc43.noarch from f43-build

Please rebuild tmt.

Comment 1 Petr Šplíchal 2025-06-16 16:38:15 UTC

This is currently blocked by the missing `python3-pydantic`: BZ#2372054

Comment 2 Mikolaj Izdebski 2025-07-07 08:16:30 UTC

python3-pydantic is available, please rebuild tmt against Python 3.14 in rawhide.

Thre is a test failure now:

which might still be an issue in pydantic.
