wine users - Jul 2010 - I can notload the APT line ppa:ubuntu-wine/ppa in 9.04

I cannot load wine .Ihave been told I need the GPG key before I can load the APT
line .How do I get the Key .
Any help will be appreciated :(  :(

sudo add-apt-repository ppa:ubuntu-wine/ppa

That's all you need to do. It automatically adds the repository AND fetches
the key this way. After this, you update the repo with a normal apt-get update.
