Help. Steam wont work at all on Ubuntu 15.04 [duplicate]
So after some research, I found the solution.
Open a terminal and run these commands:
rm ~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu/libstdc++.so.6
rm ~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu/libgcc_s.so.1
