AttributeError: module 'platform' has no attribute 'linux_distribution'


platform.linux_distribution has been deprecated since version 3.5, and was removed in version 3.8: See alternative like the distro package. https://pypi.org/project/distro


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!
