Normally ia32-libs packages is replaced with some other package on 14.04. But with some hack, we can still install it.
Try the following order:
echo "deb http://old-releases.ubuntu.com/ubuntu/ raring main restricted universe multiverse" >ia32-libs-raring.list
apt-get install ia32-libs
PS: In this way, you can install
ia32-libs. However, we add the source of 13.04 instead, so, there may be some problem unknown. After install
ia32-libs, I recommend you to remove the
/etc/apt/sources.list.d, and do sudo apt-get update.
