解决方法：

Since ia32-libs is now a transitional wrapper package around the set of multiarch-enabled libraries that were previously shipped bundled in ia32-libs, all of these library packages must be installable. In a released version of Ubuntu (such as in the precise
and precise-updates pockets), packages will always be individually installable; however, multiarch imposes an additional restriction on installability: the library package must be at the exact same version across all architectures that you are installing it
for.

In one of the examples given here, the libcairo-gobject2 package is implicated. This package has recently been updated for 12.04 as an SRU; which means that trying to install ia32-libs requires the amd64 version of libcairo-gobject2 on your system to match
the i386 version that will be downloaded.

To ensure you're getting the correct versions of all library packages, do the following:

Launch Update Manager

Choose Settings at the bottom of the window

Under Updates, make sure that Recommended
Updates (precise-updates) is selected.

Click Check to scan for any new software updates

Click Install Updates to ensure your existing packages are all up to date

If you currently have a broken package installed which depends on ia32-libs, this may ask to remove it. You should proceed with the removal and reinstall once the operation is completed. You should then be able to run

sudo apt-get install ia32-libs

to install ia32-libs, or download package from http://packages.ubuntu.com/ and

sudo dpkg -i /path/to/package.deb

sudo apt-get -f install

to install your package and automatically pull in ia32-libs as a dependency.

Note that ia32-libs is considered deprecated in any case. For most software, you should instead install the i386 version of the package and let it directly pull the i386 libraries that it needs as dependencies, instead of using ia32-libs which is a catch-all.

基本上就是更新完后就能安装了！
