Dear Maintainer,
The latest steam client cannot be executed, we get:
~~~~
$ steam
[..]
[----] Verifying installation...
[2025-11-30 11:09:11] Verification complete
UpdateUI: skip show logo
dlmopen /opt/steam/ubuntu12_32/steamui.so failed: libXtst.so.6: cannot open
shared object file: No such file or directory
dlmopen steamui.so failed: steamui.so: cannot open shared object file: No such
file or directory
Failed to load steamui.so - dlerror(): (null)
~~~~
The missing file can be located with `apt-file search libXtst.so.6`, then
aftering installing the i386 architecture of this package, the error changes to
a different missing file.
After doing this dance for a while we eventually get to:
~~~~
$ apt install libpipewire-0.3-0t64:i386 libxtst6:i386 libgtk2.0-0t64:i386
libxcb-res0:i386

Which cannot be resolved because libvpx6 is no longer in Debian - and
installing libvpx-dev:i386 does not help. It does seem to be the last one
that's missing, however.

After some playing around I realised the error occured because I did a
`sudo chmod -R g+s` on `/opt/steam` recently, which mistakenly applied
this to *files* as well as directories.
Most programs would fail open in this situation, but some of the
programs used internally by the Steam Runtime have been written more
cautiously and fail closed.
Since the 2026-01-21 Steam client update, it will fail "cleanly" in this
situation with an error message popup.
