The way you're meant to disable Upstart services is like this, in a terminal:
echo "manual" | sudo tee /etc/init/ssh.overrideBasically, to disable a service with a config file named ssh.conf, you make a plain text file named ssh.override with the word "manual".
This is what I do when I install Trisquel: echo "manual" | sudo tee /etc/init/cups.override echo "manual" | sudo tee /etc/init/smbd.override echo "manual" | sudo tee /etc/init/ssh.override sudo stop cups sudo stop smbd sudo stop ssh
