+This is great, but if you are running it on a Virtualbox, it will not work (at least it didn't work 
+2 weeks ago). The problem is I (you) lose the network connection at the initial 100+ packages 
+upgrade and you cannot finish it.
+I may try it again after the holidays, but we may need to put a warning out.
+The other option would be to download everything before the actaul upgrade.
