This is a tracking bug for Change: Changes/Unified KDE OOBE For more details, see: https://fedoraproject.org/wiki/Changes/Unified_KDE_OOBE All Fedora KDE variants will use the KDE Initial System Setup application to configure the system after installation. Anaconda will have redundant settings disabled for installation. If you encounter a bug related to this Change, please do not comment here. Instead create a new bug and set it to block this bug.
At this point, I'm waiting on the Anaconda folks to merge the profile settings for Fedora KDE: https://github.com/rhinstaller/anaconda/pull/6778
This is all implemented and QA has updated test cases for it.
