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

Wow, this saved my life. Thanks!

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:

sudo vi /etc/apt/preferences

and insert the following lines:

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

Pin-Priority must be greater than 1000.

Then you may downgrade the programs with:

sudo apt-get dist-upgrade

Then you may install packages that complained about dependencies, like

sudo apt-get install ia32-libs-multiarch

, or

sudo apt-get install ia32-libs

Finally, you should remove the file you just created:

rm /etc/apt/preferences

because else no new updates would be found.

Hope this helps you too!
