which is a bit misleading
reason – machine had no network access through NAT, what was required nor documented anywhere, instead try:
http_proxy="http://ip:port" do-release-upgradeshould work.
Thanks!

Nano would be better, even emacs. And now please please please, no DUMB!!! comment that vi is the only editor that will be installed everywhere. The next time I hear this one I am going to beat the person to death for it. And this in the age of GIGA and TERRABYTES. Apt-get install nano… what the heck???
vi is by far and away the most widely used editor in any *nix space, and the most powerful and frankly the best.
nano — why?
