I had a similar problem with broken dependencies when trying to install wine and acroread, and a complaint when trying to install ia32-libs-multiarch, 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
enter
:wq to write the file. Pin-Priority must be greater than 1000.
Then you may downgrade the offending applications 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:
sudo rm /etc/apt/preferences
because else no new updates would be found.
Hope this helps you too!
