Comment 1 for bug 2047343

The following profile worked for me, if it works for you I will get it uploaded asap. You can just drop it in a file and do

sudo apparmor_parser -r /path/to/your/file

to test it.

# This profile allows everything and only exists to give the
# application a name instead of having the label "unconfined"

abi <abi/4.0>,
include <tunables/global>

profile steam /usr/{lib/steam/bin_steam.sh,games/steam} flags=(unconfined) {
  userns,

  # Site-specific additions and overrides. See local/README for details.
  include if exists <local/steam>
}
