undo "wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add - "

Asked by Nemo

I have ran this command on a friend's computer after he requested that I installed Picasa 3.0 Beta for him:
"wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -"
Afterwards he changed his mind and decided he doesn't want the beta and now I don't know how to undo the command.
Help?

I still would like to now, how would you get rid of a wget command, because I once wrote something along the lines of "wget -q htto://.....etc" and because I wrote "htto" instead of "http", not only did it not work, for what I was going to do afterwards, but more importantly I can no longer run the command "sudo apt-get update" because the terminal returns "E: The method driver /usr/lib/apt/methods/htto could not be found" even after I opened a new terminal or even restarted Ubuntu. Can anyone please help me on how to undo a wget command? Thanks in advance :)
