Many thanks. This is truly excellent support.
The only remaining issue I have now is with kdeconnect which isn’t working (no devices found). I found an old reference to kdeconnect4 when I searched the forum but the only entry using search dnf is what I already found and installed. On some distros it’s necessary to create a firewall rule for kdeconnect but no entries appear in the application set for openmamba so I’m at a loss where to go next?
