Wine,Skype, Google Earth etc.. ia32 on 12.04.1

It seems that some PPAs have newer versions of apps than the stock 12.04. This can cause nightmares when you go to install stuff that needs the ia32 mutliarch stuff because the 386 version has to be the same as the amd64 version.

After a couple of days of trying to resolve the packages by hand and force versions I came across this post that uses apt-pinning in the preferences to downgrade everything to stock.  http://ubuntuforums.org/showpost.php?p=12246372&postcount=7

Once running stock packages, Wine, skype etc should install....

Re: ia32-libs error [Cant install on amd64]ia32-libs error [Cant install on amd64]

I had a similar problem with broken dependencies when trying to install wine and acroread, just after upgrading to 12.04 from 11.04 (passing over 11.10). It seems that some ppa's I had in 11.04 installed newer versions of applications in the system. After upgrading, the remains of these apps seemed to do some mess in the dependencies.

The solution that seems to work (until now), was found on a german ubuntu board ( http://forum.ubuntuusers.de, posts from user Lasall):

First a downgrade is required and done with the following: create the 'preferences' file: Code:

sudo vi /etc/apt/preferences

and insert the following lines: Code:

Package: *       
Pin: release a=precise*
Pin-Priority: 2012

Pin-Priority must be greater than 1000.

Then you may downgrade the programs with: Code:

sudo apt-get dist-upgrade

Then you may install packages that complained about dependencies, like Code:

sudo apt-get install ia32-libs-multiarch

Finally, you should remove the file you just created: Code:

rm /etc/apt/preferences

because else no new updates would be found.

Hope this helps you too!
