How to Upgrade from Ubuntu 7.10..

Support for Ubuntu 7.10 ended in April 2009 and the incremental upgrade method is only available from one release to another. There are two options I can think of however. The first would be to upgrade to Ubuntu 8.04 LTS and then upgrade to Ubuntu 10.04 LTS (still in development)

Here are the steps for using this method. First you would need to replace all the default Ubuntu 7.10 repositories

Open a Terminal and submit the following command

sudo gedit /etc/apt/sources.list

Delete all the default Ubuntu 7.10 (gutsy) repositories and replace them with these

deb http://old-releases.ubuntu.com/ubuntu/ gutsy main restricted
deb-src http://old-releases.ubuntu.com/ubuntu/ gutsy main restricted
deb http://old-releases.ubuntu.com/ubuntu/ gutsy-updates main restricted
deb-src http://old-releases.ubuntu.com/ubuntu/ gutsy-updates main restricted
deb http://old-releases.ubuntu.com/ubuntu/ gutsy universe
deb-src http://old-releases.ubuntu.com/ubuntu/ gutsy universe
deb http://old-releases.ubuntu.com/ubuntu/ gutsy-updates universe
deb-src http://old-releases.ubuntu.com/ubuntu/ gutsy-updates universe
deb http://old-releases.ubuntu.com/ubuntu/ gutsy multiverse
deb-src http://old-releases.ubuntu.com/ubuntu/ gutsy multiverse
deb http://old-releases.ubuntu.com/ubuntu/ gutsy-updates multiverse
deb-src http://old-releases.ubuntu.com/ubuntu/ gutsy-updates multiverse

After you have done this click save in the top left hand corner and close the window.

Back in the Terminal submit

sudo apt-get update

This will add the repositories to the Ubuntu 7.10 installation. Open the Update Manager and apply any updates that are suggested. DO NOT select upgrade to Ubuntu 8.04 LTS if you get a notification at this stage

Once you have applied updates Reboot your PC/Laptop then open Update Manager again

You will be notified that a (New Distribution Release 8.04) is available

Go ahead and select that. The system upgrader with a Broadband connection usually takes around half an hour I have found through experience

Once Ubuntu 8.04 LTS is fully installed Reboot after which it is time to upgrade from Ubuntu 8.04 LTS to Ubuntu 10.04 LTS

Press Alt-F2 then type update-manager --devel-release

This command will open the Update Manager

Check for new updates. Once you have applied updates Reboot then open Update Manager again

As before you will be notified that a (New Distribution Release 10.04) is available. Go ahead and run the upgrader once again.

The whole process should take around 1-2 hours with a Broadband connection

Alternatively you have the option to directly replace Ubuntu 7.10 with Ubuntu 9.10 which will mean erasing the Ubuntu partition
