It is not important whether the problem is relevant to Python 3.8, this issue is blocking the Python 3.8 rebuilds.
If this package won't build with 3.8, it won't be installable, along with all its dependent packages, in Fedora 32 and further.

Furthermore, as it fails to install, its dependent packages will fail to install and/or build as well.

Please rebuild the package in Fedora 32 (rawhide).

Let us know here if you have any questions. Thank You!
Comment 1 Miro Hrončok 2019-11-25 10:27:27 UTC 
What is the plan here? Do we try to keep the package or retire it?

Please respond.
Comment 3 Ankur Sinha (FranciscoD) 2019-12-10 17:41:48 UTC
