This is only severe because pycurl needs pyflakes. That can be changed: https://src.fedoraproject.org/rpms/python-pycurl/pull-request/3 This comment is mass posted to all bugs blocking the Python 3.9 tracker, sorry if it is not 100 % relevant. When in doubt, please ask.
The Python 3.9 rebuild is in progress in a Koji side tag.
If you fix this bug, please don't rebuild the package in regular rawhide, but do it in the side tag with:
$ fedpkg build --target=f33-python
The rebuild is progressing slowly and it is possible this package won't have all the required build dependencies yet. If that's the case, please just leave the fix committed and pushed and we will eventually rebuild it for you.
You are not asked to go and try rebuild all the missing dependencies yourself. If you know there is a bootstrap loop in the dependencies, let me know and we can untangle it together.
If you want to test your fix or reproduce the failure, you can still use the Copr repo mentioned in the initial comment of this bug: https://copr.fedorainfracloud.org/coprs/g/python/python3.9/
Python 3.9 update: The f33-python side tag is currently being merged.
New builds in f33-python are no longer possible, but python3 is not yet updated to Python 3.9 in rawhide. You can check when Python is Python 3.9 with:
$ koji wait-repo f33-build --build python3.9-3.9.0~b1-3.fc3
And build the packages normally after that.
*** Bug 1841662 has been marked as a duplicate of this bug. *** I've no capacity for handling this in a short loop, help on this will be appreciated. Hello, This is the first reminder (step 3 from https://docs.fedoraproject.org/en-US/fesco/Fails_to_build_from_source_Fails_to_install/#_package_removal_for_long_standing_ftbfs_and_fti_bugs). Any package buildrequiring pyflakes/flake8 just to lint the code in %check may just stop doing that. I can help. Upstream report: https://github.com/PyCQA/pyflakes/issues/549 I'm going to skip the few affected test for now to unblock others. Note: Some of these were bugs in cpython introduced by the PEG parser: https://bugs.python.org/issue40334 (In reply to Miro Hrončok from comment #9) > https://src.fedoraproject.org/rpms/pyflakes/pull-request/10 This has been merged The package built. Keeping this open to track the workaround. Hello, This is the first reminder (step 3 from https://docs.fedoraproject.org/en-US/fesco/Fails_to_build_from_source_Fails_to_install/#_package_removal_for_long_standing_ftbfs_and_fti_bugs). (In reply to Igor Raits from comment #13) > Hello, > > This is the first reminder (step 3 from > https://docs.fedoraproject.org/en-US/fesco/ > Fails_to_build_from_source_Fails_to_install/ > #_package_removal_for_long_standing_ftbfs_and_fti_bugs). I've reported this comment as bogus to Igor. This is a bulk close of Python 3.9 bugzillas of packages that successfully built. If this remained open for a reason, I am sorry and feel free to reopen. |

You can follow these instructions to test locally in mock if your package builds with Python 3.9: https://copr.fedorainfracloud.org/coprs/g/python/python3.9/ Let us know here if you have any questions. Python 3.9 will be included in Fedora 33. To make that update smoother, we're building Fedora packages with early pre-releases of Python 3.9. A build failure prevents us from testing all dependent packages (transitive [Build]Requires), so if this package is required a lot, it's important for us to get it fixed soon. We'd appreciate help from the people who know this package best, but if you don't want to work on this now, let us know so we can try to work around it on our side.
