I am testing Ubuntu 13.04 ARM on my Android phone. I want to try using Cisco Packet Tracer, I have installed it but it needs ia32-libs-gtk package to work. I tried to do
sudo dpkg --add-architecture i386 && sudo apt-get update && sudo apt-get install ia32-libs-gtk:i386
but still I can't get that package because "E: Unable to locate package ia32-libs-gtk". I am new at using Ubuntu. I was "Googling" about that problem like for half an hour but what I mostly saw is some old (~2011) topics not really helping. How can I install that package?
