I had a look in var/lib/apt/lists The package that had warned DO NOT INSTALL ON A REAL SYSTEM EVER was mentioned. release-upgrade-apt was in synaptic, but it wasn't installed. release-upgrade-dpkg wasn't there. ( I know better now than to get the bright idea to do install THAT.) Sources couldn't verify the signature. Still sometimes an experiment can blow up in your face, sometimes you get penicillin. I'm getting a new laptop in March. You probably know whats in the list, but I'll send a copy. I pasted the lists together on to the one text file. My dog wants a chewy bone.
