This procedure is intended for people who wants to upgrade from an existing Ubuntu 9.04 hard drive install.  If instead you want to upgrade (or do a fresh install) using Ubuntu 9.10 Desktop CD, refer to the following Ubuntu website article:  Upgrading to Ubuntu 9.10

If you already have Ubuntu 9.04 installed, there is an easy way to upgrade directly from the Internet without the need of Ubuntu 9.10 Install CD. 

First, boot your computer in Ubuntu 9.04. Then do the following steps:

  • Open a terminal (Applications | Accessories | Terminal)
  • Enter the following command to update the package list:
sudo apt-get update
  • Then make sure Update Manager is installed and up to date:
sudo apt-get install update-manager
Lauch Update Manager: 

sudo update-manager -d
  • You will see an option “New distribution release ‘9.10′ is available”.  Click the Upgrade button to upgrade and follow the prompts to upgrade your distribution.

Now, seat back and relax because Update Manager will take a while to download all the required packages from the Internet and to install them.
