Adding the WineHQ APT Repository:
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/sources.list.d/feisty.list -O /etc/apt/sources.list.d/winehq.list
For Ubuntu Edgy (6.10): *64-bit packages not available*
sudo wget http://wine.budgetdedicated.com/apt/sources.list.d/edgy.list -O /etc/apt/sources.list.d/winehq.list
For Ubuntu Dapper (6.06): *64-bit packages not available*
sudo wget http://wine.budgetdedicated.com/apt/sources.list.d/dapper.list -O /etc/apt/sources.list.d/winehq.list
For Debian Etch (4.0): *64-bit packages not available*
sudo wget http://wine.budgetdedicated.com/apt/sources.list.d/etch.list -O /etc/apt/sources.list.d/winehq.list
Then, you can install Wine from WineHQ like it were any other package, such as by using the Synaptic Package Manager under System->Administration. Alternatively, you can install from the terminal by running 'sudo apt-get update' to update APT's package information and then 'sudo apt-get install wine'.
