Description of problem: Fedora 22 is planning to switch over to dnf from yum as per https://fedoraproject.org/wiki/Changes/ReplaceYumWithDNF Please switch from yum/yum-utils to dnf/dnf-plugins-core. Thanks!
Thanks. I am working on this. Once dnf-langpacks is complete I will move to system-config-language to port it to use dnf/dnf-langpacks.
This is done now.
