Hi I am new to linux and ubuntu and have installed ubuntu on a machine so I can muck around with it. I have been trying to install wine as well. On the wine website it says to:

"First, open a terminal window. Then add the repository's key to your system's list of trusted APT keys by copy and pasting the following:
wget -q http://wine.budgetdedicated.com/apt/387EE263.gpg -O- | sudo apt-key add -
Next, add the repository to your system's list of APT sources:
For Ubuntu Feisty (7.04):
sudo wget http://wine.budgetdedicated.com/apt/....d/feisty.list -O /etc/apt/sources.list.d/winehq.list
For Ubuntu Edgy (6.10):
sudo wget http://wine.budgetdedicated.com/apt/...st.d/edgy.list -O /etc/apt/sources.list.d/winehq.list
For Ubuntu Dapper (6.06):
sudo wget http://wine.budgetdedicated.com/apt/....d/dapper.list -O /etc/apt/sources.list.d/winehq.list"


I have tried doing that for my ubuntu vs which is 6.10 but the problem is that when i do the "wget -q http://wine.budgetdedicated.com/apt/387EE263.gpg -O- | sudo apt-key add -" command it says there is no such thing as apt-key.

Any pointers on this? I am new to all this and may be missing something as the only linux command I know in the terminal is "exit".
thanks in advanced
