Dear package maintainer, this bugzilla is automated becasue the number of impacted packages it too high to go trough manually. It appears that your package uses the deprecated %py3_build and/or %py3_install macro. See https://fedoraproject.org/wiki/Changes/DeprecateSetuppyMacros for why the macros are deprecated. %py3_install expands to python setup.py install. This has been a deprecated command for 5 years and will likely stop working in Fedora 45. Please migrate to %pyproject_buildrequires + %pyproject_wheel + %pyproject_install macros instead. See https://fedoraproject.org/wiki/Changes/DeprecateSetuppyMacros#Migrating_to_%pyproject_macros for migration guide. See https://github.com/hroncok/pyprojectize/ for a tool that can help you automate the migration. Thank you. Let me know if you need help.
