Upgraded Ubuntu Feisty to Ubuntu Linux 7.10 (Gutsy Gibon)

True to Ubuntu Linux form, this was painless as usual.

The following are the steps at the command line:

sudo sed -i 's/feisty/gutsy/g' /etc/apt/sources.list
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get -f install

And thats it! You're done!
