error while loading shared libraries libSDL-1.2.so.0

This worked for me:

sudo apt-get install libsdl1.2debian:i386

Try the following in terminal:

sudo apt-get update

followed by

sudo apt-get install --reinstall libsdl1.2debian

Post any error messages you might see

sudo apt-get install libsdl1.2-dev libsdl-image1.2-dev libsdl-mixer1.2-dev libsdl-ttf2.0-dev
