I have tried:
sudo add-apt-repository ppa:ubuntu-wine/ppa
sudo apt-get update
sudo apt-get install wine1.5
and it failed.
The error seems to be:
The following packages have unmet dependencies: wine1.5 : Depends: wine1.5-i386 (= 1.5.19-0ubuntu1) but it is not installable E: Unable to correct problems, you have held broken packages.
wine1.5-i386 but its not on Ubuntu, so I can't install wine because
wine1.5-i386 is part of it. When I try to get wine in the Ubuntu Store I get the same error with less details.
