the "Installing Popular Applications On Your Ubuntu Desktop With Automatix2 - Page 2" there is a problem for novice users:
echo "deb http://www.getautomatix.com/apt edgy main" | sudo tee -a /etc/apt/sources.list
gpg --import key.gpg.asc
gpg --export --armor 521A9C7C | sudo apt-key add -
apparently has a line break before the /etc/apt/sources/.list. I entered the first line, and then hit enter. This was apparently wrong, because "/etc/apt/sources.list" apparently has no meaning as a linux command. I hope there was no damage done. I figured that I needed to enter both lines on one line and did it again.
Altering the instructions to indicate the line break, or removing the line break would solve this problem.
