Рекомендация с официального сайта WINE

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, 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'.
