Yes, thank you for that clarification, Colin.

What I do expect is some reaction, even if it is not the right one.
When I click on it, I get nothing at all.

This happens on my desktop, on which I freshly installed 20.04 from
the iso, and on all the other machines I have upgraded from 18.04.

Here is what happens from the command line:

$ man -k software-properties
software-properties-gtk (1) - Software Sources List editor
$ software-properties-gtk
ERROR:dbus.proxies:Introspect error on :1.329:/:

Sure looks like a bug to me...  :-}

Thanks.
