Your system information

Steam client version (build number or date): June 4, 2020
Distribution (e.g. Ubuntu): Arch Linux
Opted into Steam client beta?: No
Have you checked for system updates?: Yes

Please describe your issue in as much detail as possible:

I get this error when I try to run /usr/bin/steam:

/usr/bin/steam: /usr/lib/steam/steam: /usr/bin/env: bad interpreter: Permission denied
/usr/bin/steam: line 2: /usr/lib/steam/steam: Success

Running sh /usr/bin/steam is fine.
I have checked that sh and bash are symlinked and discovered by env correctly:

$ type -a sh
sh is /usr/bin/sh
$ type -a bash
bash is /usr/bin/bash
$ getfacl /usr/bin/env
getfacl: Removing leading '/' from absolute path names
# file: usr/bin/env
# owner: root
# group: root
user::rwx
group::r-x
other::r-x

Also, I am sure that noexec is not set on my file system. Other shebang scripts run without problem. In addition, other of my machines run the /usr/bin/steam script without issue. I'm out of ideas now, so I wonder what could be wrong here.

I use ZFS for my device; / and /home are datasets/subvolumes in my ZFS pool. I have no idea if this could be the culprit and it seems unlikely, but this might be it.

Steps for reproducing this issue:

Run /usr/bin/steam

Arch maintains the steam installer for their distribution, this should probably be reported through their channels.

CNR in any case (on Manjaro). The symlinks and trampoline scripts end up at /usr/lib/steam/bin_steam.sh - that's the script with the /usr/bin/env failing for you.

@TTimo : Hello, I did file a bug report on Arch Linux bug tracker, and the Arch maintainers were unable to replicate or track down the bug. As a recourse they recommended that I open a bug here.

I think I found it. I had exactly the same error under following conditions:

Arch Linux
FireJail 0.9.68
Apparmor installed, loaded and firejail-default enforced
I had apparmor set in ~/.config/firejail/globals.local (or /etc/config/firejail/globals.local)

This resulted in exactly the same error. I "fixed" it by disabling firejail-apparmor for steam by creating following file:

~/.config/firejail/steam.local:

ignore apparmor

Now steam-runtime as well as steam-native works.

Hello @xuanruiqi, are you still experiencing this issue on an up to date system? Were you also trying to run Steam with firejail?

Closing pending feedback.

On Arch Linux, using apparmor, and firejail, the default steam profile tries to execute this script and it cannot.

/usr/lib/steam/steam: /home/andrew/.local/share/Steam/steam.sh: /usr/bin/env: bad interpreter: Permission denied
/usr/lib/steam/steam: line 216: /home/andrew/.local/share/Steam/steam.sh: Success
[ 2274.886072] audit: type=1400 audit(1710056212.443:249): apparmor="DENIED" operation="exec" class="file" profile="firejail-default" name="/home/andrew/.local/share/Steam/steam.sh" pid=176569 comm="bash" requested_mask="x" denied_mask="x" fsuid=1000 ouid=1000

As noted, adding 'ignore apparmor' to the steam.local "solves" the problem by disabling apparmor, but a better way would be to whitelist or allow exec that shell script, but I don't really know how. It involves a firejail configuration directive I think.
