Fix for Steam: "Missing 32-bit libraries: libGL.so.1"

[masterg2]

For those who're being displayed this error even after following the suggestions from the posts above, try this:

sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/libGL.so.1

The problem is that the necessary 32-bit libraries can't be found by Steam on 64-bit Ubuntu (and its derivatives).

Hello all,

I add my own feedback, even if the post is old and has been [SOLVED], because I still encounter the error under Ubuntu Mate 16.04 and have found a shortcut so solve.

After installing original Ubuntu steam package ("sudo apt-get install steam"), the soft has laucnhed a first time, then successfully updated itself automatically.
At second lunch try, the libraries error has come up.

In my case, the "sudo ln -s ..." command indicated by erikroyall (many thanks!!!) has been enough for Steam to launch normally.

So, for a fresh install, just type these:

sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/libGL.so.1

sudo apt-get install steam

Hope this can simplify a bit all attempts to come

Regards!

I was able to fix it with:

apt install nvidia-driver-libs:i386

got that error after upgrading to nvidia drivers 418.40 :

ldconfig -p | grep libGL.s
libGL.so.1 (libc6,x86-64) => /usr/lib32/nvidia-418/libGL.so.1 < BUG : that lib is supposed to be 32b !
libGL.so.1 (libc6,x86-64) => /usr/lib/nvidia-418/libGL.so.1
libGL.so (libc6,x86-64) => /usr/lib32/nvidia-418/libGL.so
libGL.so (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libGL.so
libGL.so (libc6,x86-64) => /usr/lib/nvidia-418/libGL.so

expected:
libGL.so.1 (libc6,x86-64) => /usr/lib/nvidia-418/libGL.so.1
libGL.so.1 (libc6) => /usr/lib32/nvidia-418/libGL.so.1

Upgrading to 418.56 seems to make steam work again.
