You can try this to install 32 lib(not all in ia32-libs): apt-get install program:i386.
Or if you want to install the whole ia32-lib instead, try the following order:
sudo -i
cd /etc/apt/sources.list.d
echo "deb http://old-releases.ubuntu.com/ubuntu/ raring main restricted universe multiverse" >ia32-libs-raring.list
apt-get update
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 ia32-libs-raring.list in /etc/apt/sources.list.d, and do sudo apt-get update.
