1. make sure you know where your .iso file is located, perhaps /home/me/download/ubuntu-7.04-alternate-i386.iso 2. make a directory to mount it. eg mkdir /mnt/ubuntu-cd 3. add an entry in /etc/fstab reading something like # Ubuntu CD #path-to-file mount-point parameters... /home/me/download/ubuntu-7.04-alternate-i386.iso /mnt/ubuntu-cd auto noauto,loop,ro,exec 0 0 4. mount the filesystem mount /mnt/ubuntu-cd You can then point apt (and friends) at this mount point instead of your normal CD mount point (/media/cdrom, I think), and bob's your uncle. > This only did about 3/4 of the upgrade, the rest had to be done direct > from the repositories (another 250Mb ish).

The package cache is /var/cache/apt/packages. When you do an installation or upgrade, apt (and its various front-ends) looks for packages in the package cache first, and only downloads them if they are not there. This is useful if you have one machine with a good internet connection (perhaps you have broadband at home), and other machines with a slow connection (if you only have dialup at work).
