Hello @purplerider, your terminal spew reads like #5463, can you move ~/.local/share/Steam/ubuntu12_32/steam-runtime/pinned_libs* out of the way and see if it makes a difference? If it does, please list the contents of the old and new pinned libs folders.
Steam works now, thanks!
Here's a screencap of the old and new pinned libs folders. The old are on top and their respective new ones are below them.
Thanks again!

I have the same issue. removing the pinned_libs directory does not fix the issue for me.
here is my output (initial isntallation, deletion of pinned libs and another try:
# Die Option »-e« ist veraltet und wird in einer späteren Version von GNOME-Terminal entfernt.
# Verwenden Sie »-- «, um die Optionen abzubrechen. Schreiben Sie die auszuführende Befehlszeile dahinter, die ausgeführt werden soll.

Hello @dakky, your issue is unrelated to the opening post.
This is the line of interest in your terminal spew:
libGL error: failed to load driver: swrast
Swrast is mesa's slower software renderer and since steam is trying to use it, that indicates you most likely do not have a sane 32 bit opengl driver installed.
Nothing extracted yet.
Hi there, my issue is that for some reason when I launch Steam the little window comes up that says verifying install then crashes. I tried restarting my system and nothing improved. Tried reinstalling and it does the same thing.
This is what I get when I try to run it from a command line:
