installation - What packages do I install to get WINE in 12.04?

I have Ubuntu 12.04 64bit.

I tried to install WINE in 11.10 but met with some difficulties because of which I removed it. I tried to install Assassin's Creed 1 but turned to be a catastrophe.

Now I want to try again. However, I am confused as to which of these packages am I to install, avoiding crashes, clashes, system failures system damage and ensuring running smooth installation of games.

I need help regarding compatibility and dependency.

I viewed this answer and as per the update & want the latest developing branch.

On trying to install wine through terminal, I get this error :

ved [ ~ ] >>>> sudo apt-get install wine

Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.
The following information may help to resolve the situation:

libglu1-mesa-dev : Depends: libglu1-mesa (= 8.0.4-0ubuntu0.2) but 9.0.0-0ubuntu1~precise1 is to be installed
E: Build-dependencies for wine could not be satisfied.

I tried to install dependencies but no success. Also, sudo apt-get -f install didn't work. If I run sudo apt-get -f install wine1.5, it gives unmet dependency as

The following packages have unmet dependencies:
wine1.5 : Depends: wine1.5-i386 (= 1.5.20-0ubuntu2)
E: Unable to correct problems, you have held broken packages.

and on attempting to install wine1.5-i386,

The following packages have unmet dependencies:
wine1.5-i386:i386 : Depends: libgl1-mesa-glx:i386 but it is not going to be installed or
libgl1:i386
Depends: libglu1-mesa:i386 but it is not going to be installed or
libglu1:i386

What else do I do?
