cannot talk to klauncher the name org.kde.klauncher5 was not provided by any .service files
This error message is typically returned by KDE applications that are running outside of KDE and are trying to access remote files.
It seems to be the result of the kio system not being installed. Installing the following modules seems to fix the problem:
- kio - the error message changes: now it doesn't recognize the sftp: protocol
- kio-extras - fixes the problem
