Hello all I'm running Ubuntu 12.04 LTS in a 64-bit version. After hours and hours of reading and going through many forums, I'm still confused about running 32-bit applications. What I figured out is, that my Ubuntu is multi architecture enabled: dpkg --print-foreign-architectures gives me: i386. However, if I want to run some 32 bit applications, I don't know which package of 32-libs I really need? ia32-libs-multiarch or ia32-libs or even ia32-lib-i386 ? Can somebody please explain me the difference? Thank you very much for clarification.
