Void Linux: No windows in steam

[ghost]

On Void Linux, I created a steam instance through bubblejail-config called "steam" and left all the options on their default options. After that, I run steam through: bubblejail run steam I am then able to log in without any issues, but once I have logged in and the steam window opens, steam doesn't display Library, Store, etc.

Hello,

1. Does it happens when running steam outside of bubblejail? (you can try separate linux user to test that)
2. Can it always be replicated? Steam is pretty buggy and can sometimes fail to load.
3. Have you tried running bubblejail steam through terminal to check if there are any relevant logs?

[ghost]

This problem is not present outside of bubblejail, and it consistently occurs when running steam under bubblejail.

Steam.log

Well the only thing I see that might fit is:

  65   │ steamwebhelper.sh[277]: Runtime for steamwebhelper: defaulting to /home/$USERNAME/.local/share/Steam/ubuntu12_64/steam-runtime-heavy
  66   │ steamwebhelper.sh[277]: Using CEF sandbox (try with -no-cef-sandbox if this fails)
  67   │ Aborted

Sadly, this issue persists.

Sadly I can't help you with debugging this issue. I don't run Void Linux.

If you want to debug it. Try using strace and --debug-bwrap-args to find out what exactly is missing.

Also:

process 126: D-Bus library appears to be incorrectly set up; failed to read machine uuid: Failed to open "/etc/machine-id": No such file or directory

Does that file exist outside sandbox? Are you running D-Bus?

[ghost]

Yes, D-Bus is running, both as root and normal user, and the error is not present outside of bubblejail. I will try and see if I can find what causes this issue later.

[igo95862]

BTW is /etc/machine-id a symlink?

Also what version of bubblejail are you running? (run bubblejail --version)

[ghost]

I ran into this issue on Void Linux as well. To fix this, I passed /var/lib/dbus/machine-id as a readonly directory and Steam worked properly afterwards. /etc/machine-id doesn't exist on my install of Void Linux.

[ghost]

Thanks! This fixes the issue for me as well. /etc/machine-id does not exist for me either.

[igo95862]

@NymanMatthias thank you for finding the solution!

[igo95862]

@junkmanner BTW how did you install the bubblejail? Is it from source? Is there an AUR-like package?

Can whoever packaged it add a patch to bind /var/lib/dbus/machine-id inside sandbox? It feels like a Void specifc issue so I don't feel like altering the actual source code to just fix one particular distro.

[ghost]

@igo95862 Bubblejail is not officially packaged on void, however, void does allow you to create and package unofficial packages using xbps-src (like makepkg on arch).

I am unsure how @junkmanner installed bubblejail, but I have made a template, which can be used to install bubblejail through void's package manager.

For people using void who might stumble upon this in the future, here is the template I use, and a patch for steam.toml that fixes the steam dbus issue. Template:

I think that Steam is not the only application that will have issues with the missing machine id.

I would have a patch something like this:

diff --git a/src/bubblejail/services.py b/src/bubblejail/services.py

--- a/src/bubblejail/services.py

This way the machine id is always passed.

So far, I have only used bubblejail's profiles for steam, firefox, chromium, and the generic profile with discord, but so far, only steam had this machine-id problem, so I am unsure if programs other than steam need /var/lib/dbus/machine-id to be passed on void.

[ghost]

@igo95862 @NymanMatthias I just built it from source

[igo95862]

I documented the missing machine-id file in the this file. There is also now a link to this file in README.

[ghost]

Looks good! AFAICT, /etc/machine-id is a systemd specific file, so this issue might be present on other distros without systemd.

Looks good! AFAICT, /etc/machine-id is a systemd specific file, so this issue might be present on other distros without systemd.

It is present on Alpine Linux but they maybe introduced it for compatibility.

[ghost]

I saw a bit of discussion about it for Alpine, but that is a bit old, and /etc/machine-id might have been added since then.
