After years using knode, I installed Mint 18 where it is not available and eventually selected Pan as a substitute.
It installed UK and came up but after entering details of two news servers and their respective requirementas,
no lists came down.

I just tried executing from a terminal and got this:

DBus.Errorrg.freedesktop.DBus.Error.ServiceUnknown: The name news.pan.NZB was not provided by any .service files

Does anyone know what this implies?
