pygal itself builds fine with Python 3.10, because it has tests commented out from spec, but dependent packages (at least datagrepper) are broken.

Comment 1 Ben Cotton 2021-02-09 16:06:05 UTC

This bug appears to have been reported against 'rawhide' during the Fedora 34 development cycle.
Changing version to 34.

Comment 2 Karthikeyan Singaravelan 2021-02-17 15:52:23 UTC

Seems to be fixed upstream in https://github.com/Kozea/pygal/commit/7796f14c80fe82b9435cdc33b7d2939c8331d649

Comment 3 Miro Hrončok 2021-06-04 20:16:04 UTC

This is a mass-posted update. Sorry if it is not 100% accurate to this bugzilla.


The Python 3.10 rebuild is in progress in a Koji side tag. If you manage to fix the problem, please commit the fix in the rawhide branch, but don't build the package in regular rawhide.

You can either build the package in the side tag, with:

    $ fedpkg build --target=f35-python

Or you can the build and we will eventually build it for you.

Note that the rebuild is still in progress, so not all (build) dependencies of this package might be available right away.

Thanks.

If you have general questions about the rebuild, please use this mailing list thread: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/thread/G47SGOYIQLRDTWGOSLSWERZSSHXDEDH5/

Comment 4 Miro Hrončok 2021-06-07 23:00:23 UTC

The f35-python side tag has been merged to Rawhide. From now on, build as you would normally build.

Comment 5 Tomáš Hrnčiar 2021-06-18 08:13:51 UTC

PR: https://src.fedoraproject.org/rpms/python-pygal/pull-request/2

Comment 6 Kevin Fenzi 2021-06-19 15:32:18 UTC

Merged the PR and did a build. :) 

Many thanks for the patch!
