Steam won't launch under Ubuntu bug

From Daco.tech Technical Documentation

According to this bug report, it's due to an outdated library.

How to fix it

Rename or move the file libstdc++.so.6

The exact location of that file may vary depending on your system.

On my system, to find that file, I did:

sudo find ~/.steam -iname 'libstdc++.so.6'

Result:

/home/doc/.steam/ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu/libstdc++.so.6
/home/doc/.steam/ubuntu12_32/steam-runtime/amd64/usr/lib/x86_64-linux-gnu/libstdc++.so.6

Rename or move these two files.

Steam should launch correctly.
