upgdrading ubuntu 9.04 to ubuntu 9.10 with cdrom

This document provides instructions and notes on upgrading to Ubuntu 9.10 (code name "Karmic Koala"), the most recent release of Ubuntu, released on the 29th of October 2009.  

Before You Start

• You can only directly upgrade to Ubuntu 9.10 from Ubuntu 9.04 (see UpgradeNotes).
  
• Be sure that you have all updates applied to Ubuntu 9.04 before you upgrade.
• Before upgrading it is recommended that you read the release notes for Ubuntu 9.10, which document caveats and workarounds for known issues in this version.
  

If you have a version of Ubuntu which was released before Ubuntu 9.04, please see UpgradeNotes for information on how to upgrade.

1. Download the alternate installation CD
   
2. Burn the ISO to a CD and insert it into the CD-ROM drive of the computer to be upgraded.
   
   • If the ISO file is on the computer to be upgraded, you could avoid wasting a CD by mounting the ISO as a drive with a command like:
     

     sudo mount -o loop ~/Desktop/ubuntu-9.10-alternate-i386.iso /media/cdrom0

3. A dialog will be displayed offering you the opportunity to upgrade using that CD.

kdesudo "sh /cdrom/cdromupgrade"
