Sometimes, you may want to run 32 bit applications on Ubuntu 14.04 LTS 64 bit Operating System. To do that, earlier ia32-libs had to be installed. But since 14.04 LTS, the following must be installed instead. To install, open a terminal window and type the command below:
$ sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 lib32stdc++6
<enter>
;
