For the build logs, see: https://copr-be.cloud.fedoraproject.org/results/@python/python3.8/fedora-rawhide-x86_64/00964915-python-fsleyes/ For all our attempts to build python-fsleyes with Python 3.8, see: https://copr.fedorainfracloud.org/coprs/g/python/python3.8/package/python-fsleyes/ Testing and mass rebuild of packages is happening in copr. You can follow these instructions to test locally in mock if your package builds with Python 3.8: https://copr.fedorainfracloud.org/coprs/g/python/python3.8/ Let us know here if you have any questions.
