    I tried this but on running do-release-upgrade got:

    Checking for a new ubuntu release
    No new release found

    Editing /etc/update-manager/release-upgrades to change Prompt=lts to Prompt=normal allowed do-release-upgrade to offer an update to 8.10

    i got

    Checking for a new ubuntu release
    No new release found

    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-upgrade

    should work.

    Not cool that you peddle the vi editor as a standard to edit text files. Ever watched a newbie use that? Ever heard of software that is INTUITIVELY usable? Vi does not belong as the standard text editor in Ubuntu, not if you don’t want to see former Windows users throw Linux a mile wide and then give it a wide bearth. Vi gives Linux a bad name if you are a beginner. Nobody in their right mind spends days of learning a trivial text editor anymore. Not if you have a LIFE.

    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?
