Description of problem: Python3.7-pyqt4 is not provided by any package. Version-Release number of selected component (if applicable): Summary: Python bindings for Qt4 Name: PyQt4 Version: 4.12.3 Release: 4%{?dist} How reproducible: Always Steps to Reproduce: 1. # dnf install flatcam Letzte Prüfung auf abgelaufene Metadaten: vor 0:20:17 am Do 02 Mai 2019 21:06:34 CEST. Fehler: Problem: conflicting requests - nothing provides python3.7dist(pyqt4) needed by flatcam-8.5-13.20180606git46454c293a9b.fc30.noarch (try to add '--skip-broken' to skip uninstallable packages) Actual results: - install fails Expected results: - install succeeds Additional info: This may be an issue with "Provides" of PyQt4
I'd argue the problem is more with the Requires: , no idea where it's coming from, but flatcam has only: Requires: python3-PyQt4 (re-assigning to flatcam)
>I'd argue the problem is more with the Requires: , no idea where it's coming It's probably the result of last rebuild [1] which happened once python's automatically generated dependencies [2] has been enabled for >=f30. Based on above install_requires PyQt4 [3] gets automatically translated into Required: python3.7dist(pyqt4). If I'm correctly understood it we have at least two options: a) use %{?python_disable_dependency_generator} in flatcam.spec file - this will remove automatically generated "Required: python3.7dist(pyqt4)" and still use "Requires: python3-PyQt4" from the spec file. b) fix the python3-PyQt4 to provide standardized "pyqt4" name. I would personally vote for b) as it would clearly help to clean up the flatcam.spec file in the future.

Fixing the provides-section of pyqt4 would solve all of them.
Ugh, turning that on *after* the mass rebuild was a bad idea (apparently?). OK, I'll try rebuilding and see if those deps get added properly
OK, so looks like PyQt4 does not support dist-info, so this is going to have to be done *manually*, if at all. I'm not sure why/how PyQt4 apps like flatcam expect it to exist. From reading, https://docs.fedoraproject.org/en-US/packaging-guidelines/Python/#_automatically_generated_dependencies I dont' see any macro to support his either. I see: Provides: %{py3_dist pyqt4} but that'll only generate: Provides: python3dist(pyqt4) I suppose I could try a little more ugly: Provides: python%{python3_version}dist(pyqt4)

@Rex, I have been able to install flatcam and it installed the PyQt4 packages from updates-testing without complaining. Flatcam itself started and seem to work fine. I did only some basic operations though. Thank you for modifying the provides section to have that sorted out.
