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

For me this was solved by:

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

  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



Change the settings here:

Same thing happened twice on my pc even thought i am running ubuntu 14.04 lts. Try installing it from the terminal.

sudo apt-get install steam
