ia32-libs isn’t an installable package by default anymore, thankfully a kind poster over at stackoverflow posted a simple solution to get the libraries installed. This is useful if you are running an older 32bit application in a 64bit only Linux.
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 rm ia32-libs-raring.list
Note: Others on that same page say this isn’t a good idea, although they don’t clarify exactly why. So, this is your warning, works for me, may break things, your mileage may vary, etc.
