Wow, it's impressive that updating from one release of Ubuntu Linux to another can be filed under a Quick Tip. Those guys have done a tremendous job! I think I spent a week setting up and fiddling with FreeBSD before I realized that I couldn't upgrade from 6.3 to 7.0 without pulling my hair out. But this is Ubuntu linux so it's way easier. Here's all you have to do to upgrade from Gutsy to Hardy:



sudo apt-get install update-manager-core
sudo passwd root

At this point you need to pick a root password. Do us all a favor and pick something secure

Next up is logging in as root OR just typing su - and then entering your fabulous secure root password. Finally, issue this command and follow the on screen instructions:

do-release-upgrade

This procedure is different than than one we used to upgrade from Feisty to Gutsy so don't follow that method this time around! You can see all this instructional goodness on the official Ubuntu Wiki as well.
