Install Wine on Debian

Fuente: http://ask.xmodulo.com/install-wine-linux.html

Since Wine is included in the default repository of Debian, you can install it with apt-get. However, if you are using 64-bit Debian, you need to enable multi-architecture, as Wine is a 32-bit application.

On 64-bit Debian:

$ sudo dpkg --add-architecture i386
$ sudo apt-get update
$ sudo apt-get install wine-bin:i386 

 

On 32-bit Debian:

$ sudo apt-get install wine
