How do I install wine?
You can install wine
using the Ubuntu Software Centre and search for "wine", select the first one and press install. Also you can install PlayOnLinux which is a GUI for helping you install Windows Software into Ubuntu Linux.
Usually there are no pre-downloaded files in Linux world because you also have to find and download all the dependencies!!! That is why it is better to install programs through Software Centre that will deal with any dependencies.
You can install it through Synaptic or from the command line:
sudo apt-get install wine
You can install it via the wine PPA. In the terminal type the following:
sudo add-apt-repository ppa:ubuntu-wine/ppa
sudo apt-get update
sudo apt-get install wine wine1.8
That should leave you with the latest 1.8.x version.
