Q. How do I upgrade my server system from Ubuntu hardy heron version 8.04 to Ubuntu Linux server 8.10 Intrepid Ibex over ssh session?
A. You can do network upgrade for Ubuntu Servers from 8.04 to 8.10 using a shell prompt over remote ssh session as follows:
Ubuntu Server 8.10 Network Upgrade
Login using ssh for remote server or open console for local server

Apply patches
First, make sure your server is up to date with 8.04 version. Type the following two command to apply all upgrades:
$ sudo apt-get update
$ sudo apt-get upgrade
Change release
Open /etc/update-manager/release-upgrades file:
$ sudo bash
# vi /etc/update-manager/release-upgrades
Find line:
Prompt=lts
Change to:
Prompt=normal
Save and close the file. This will set release update from LTS (long support version) to latest 8.10 version.
Ubuntu 8.10 Server Upgrade
Type the following command to upgrade update manager, enter:
$ sudo apt-get install update-manager-core
Above will install / update update-manager-core if it is not already installed. Once installed just update system using the following command. Make sure you have backup of all important data:
$ sudo do-release-upgrade
Now, just follow the on-screen instructions.

The faq has been updated. I appreciate your post.
after
do-release-upgrade
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.
Thanks!

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?
