Adding the WineHQ APT Repository:
First, open a terminal window (Applications->Accessories->Terminal). 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 Hardy (8.04):

For Debian Etch (4.0):
sudo wget http://wine.budgetdedicated.com/apt/sources.list.d/etch.list -O /etc/apt/sources.list.d/winehq.list
Then update APT's package information by running 'sudo apt-get update'.
