Ubuntu 16.04 LTS - Steam "Fatal Error: Failed to load steamui.so"

Question

Please help. I just got this new pc with Ubuntu 16.04 LTS on it but it can't run steam. Everytime I launch it says

Fatal Error: Failed to load steamui.so.

I'm really new here so a quick and straightforward solution is greatly appreciated. It would be great if you could just provide codes for the terminal so I can simply paste them there to solve this issue.

Here's my specs

Answer 1

For me this was solved by:

1. Creating /etc/ld.so.conf.d/steam.conf with the contents:

   /usr/lib32
   /usr/lib/i386-linux-gnu/mesa
   

2. Running sudo ldconfig to update the shared library cache

3. installing/reinstalling the 32bit mesa libraries:

   sudo apt-get install --reinstall libgl1-mesa-glx:i386

Answer 2

Change the settings here:

Additional Driver → Change another driver for your graphics card.

Answer 3
