[ubuntu-us-ma] Ubuntu 9.04 to 9.10 Upgrade script extremely inefficient (downloads from the internet, ignores local CD image)

You're trying to upgrade (not recommended by me personally). During this
upgrade process, it needs to upgrade all the packages and dependencies
you have installed on your current system after the fresh install(flash,
java, restricted extras, ccsm, games, etc). This requires going online
since almost none of the packages you installed are on the CD and were
more than likely from the universe or multiverse repositories.

Regardless, I highly suggest backing up /home and creating a list of
installed packages 'sudo dpkg --get-selections > packagesinstalled.txt'
and then installing 9.10 from scratch.
