I also had this problem and was able to fix it. I imagine the solution for each person will be different.
Find reverse dependencies: $ apt-cache rdepends ia32-libs For each of those dependencies, try one by one purging them: For example: $ sudo apt-get purge google-talkplugin Of course, do due diligence and make sure purging that package is okay. Some of the packages may not even be installed. Then try re-installing... $ sudo apt-get install ia32-libs -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1016294 Title: ia32-libs-multiarch but it is not installable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ia32-libs/+bug/1016294/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
