Please describe your issue in as much detail as possible:

Steam startup fails with error "Could not load module 'vgui2_s.so'

I looks like that libsndio.so.7 is not found:

~/.local/share/Steam/ubuntu12_32$ LD_LIBRARY_PATH="$LD_LIBRARY_PATH:." ./steam-runtime/run.sh ldd vgui2_s.so|grep found
	libsndio.so.7 => not found

Generating a symbolic link in ~/.local/share/Steam/ubuntu12_32/libsndio.so.7 does not help.

Hello @oe8bck. can you check if the host system provides the 32 bit variant of this library with something like apt policy libsndio7.0:i386?

If it isn't, I'd try asking apt to install it along with the 64 bit variant so if there's a version mismatch between architectures, it'll fail instead of doing bad things. That would be something like sudo apt install libsndio7.0 libsndio7.0:i386.

Thanks @kisak-valve for your hints! I am not sure if I got you correctly, this is the output of the commands, I think these libs are installed:

$ LANG=en apt policy libsndio7.0:i386

I fixed the problem thanks to this post: https://forums.linuxmint.com/viewtopic.php?t=402670
So a simple re-install of all libsndio packages worked for me.

Glad to hear it's working for you now. That makes this either a general filesystem health issue or something went awry with apt when that package was installed.

Closing as not a Steam issue.

Nothing extracted yet.
