After leaving my Ubuntu host overnight, I've turned it on and the nut 
daemon was running when I tried the above check.  I stopped that daemon 
and the above test worked just fine!  I didn't change anything and now 
it's working just fine.

Thank you for the information about the debug test!  All OK now! :)

Cheers,
Greg
