I can’t search in discover for any of the KDE software like kmail or KDE partition manager. On the apps.kde.org website when I click the install on Linux button it pulls up discover. But it says “Could not open app stream://org.kde.whatever because it was not found in any available software repositories.”.

I have been googling for awhile and can’t figure out what repository I need or how to add it. If any one could help I would appreciate it. Thanks.
