Upgrading Ubuntu using the alternate CD/DVD

Use this method if the system being upgraded is not connected to the Internet.

1.Download and burn the alternate installation CD.
2.Insert it into your CD-ROM drive.
3.A dialog will be displayed offering you the opportunity to upgrade using that CD.

If the upgrade dialog is not displayed for any reason, you may also run the following command using Alt+F2:
