Run a 32-bit binary on a 64-bit Ubuntu

If the output of file file-name shows,

file-name: ELF 32-bit LSB  executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.x.x, not stripped

To run 32bit executable file in a 64 bit multi-arch Ubuntu system, we have to add i386 architecture and also we have to install 

libc6:i386,

libncurses5:i386,

libstdc++6:i386

these three library packages.

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386
sudo ./file-name
