Before you start
You can only
directly upgrade to Ubuntu 7.04 ("Feisty Fawn") from Ubuntu 6.10 ("Edgy Eft") (see UpgradeNotes)
Be sure that you have all updates applied to Ubuntu 6.10 before you upgrade
The latest version of Update Manager (0.45.2) must be installed before you upgrade.
Otherwise, you will receive an Authentication failed error. See here for instructions how to check if you have the required version.
Upgrading using the alternate CD/DVD
Use this method if the system being upgraded is not connected to the Internet.
Download and burn the alternate installation CD
Insert it into your CD-ROM drive
A dialog will be displayed offering you the opportunity to upgrade using that CD
Follow the on-screen instructions
If the upgrade dialog is not displayed for any reason, you may also run the following command using Alt+F2:
gksu "sh /cdrom/cdromupgrade"
