Looking into this further I realised I was wrong about packages from proposed. That was indeed the main cause of the problem. I downgraded several packages that were installed from proposed and then disbaled proposed. I have now successfully install ia32-libs (which has allowed me to install skype and google-earth). So thanks to Francis Brown..
Actually I had another issue I had to solve to get ia32-libs to install. I forgot that I had xorg-edgers ppa enabled before I upgraded from quantal to raring. It turned out that some edgers packages from quantal were newer than raring but I couldn't downgrade them from synaptic without removing a whole lot of stuff, so I enabled the xorg edgers ppa for raring and dist upgraded. I then ran pp-purge to downgrade everything back to normal raring packages. Well having proposed enabled was the main problem but this also shows that some ppa's can be troublesome when doing release upgrades. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1131487 Title: ia32-libs removed by last dist-upgrade (raring) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ia32-libs/+bug/1131487/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
