Deja Dup (DD) has worked w/o problem for 2+ years under Ubuntu Mate 18.04 - then I upgraded to 20.04 and DD no longer succeeds.
DD halts when "back up now", with window "Storage location not available. Waiting for a network connection..."
DD is configured to access a local network NAS hard disk (ethernet) using smb:// protocol
When file manager Caja mounts a NAS share, it does so using smb://, and DD is configured to access that particular smb:// share.
The DD Developer/Maintainer suggests something is not set up correctly with my networking, though I can navigate my LAN and the Internet w/o problem. I've sent him this terminal window info:

I don't know what to fix to make DD function again. Suggestions?
