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.
You shouldn’t use discover for anything other than flatpaks on Arch because it doesn’t allow manual intervention which is sometimes required on Arch. It can even leave you with an unbootable system.
