Thread: gpg: Conflicting Commands

hi, relatively new linux (have used many live disks) , have had install of ubuntu 12.04 few days now. part have found easy use , have been comfortable it.
have first question can't resolve myself: adding googles repository list. when first ran command supplied google found did not have wget installed. used apt-get install it. worked fine (as far can tell) re-ran googles code:

wget -q https://dl-ssl.google.com/linux/linux_signing_key.pub -o- | sudo apt-key add -deb http://dl.google.com/linux/deb/ stable non-free

, message 'gpg: conflicting commands' tell me going wrong , how fix please

new script :
wget -q https://dl-ssl.google.com/linux/linux_signing_key.pub -o- | sudo apt-key add linux_signing_key.pub

need edit
/etc/apt/sources.list
, add line @ end

deb http://dl.google.com/linux/deb/ stable non-free

end

hope find usefull

edit:
need root or use sudo make changes /etc/apt/sources.list
run
sudo vi /etc/apt/sources.list
or if use midnight commander (i have done long can remember)
sudo mc /wtc/apt
select sources.list , press f4 open enter line , press f2 save f10 exit out
