The SUID sandbox helper binary was found, but is not configured correctly.

Describe the bug

When running the Zulip AppImage, I cannot start Zulip.

To Reproduce

1. Install the Zulip AppImage on the target arch below
2. Run the following

> sudo chmod u+wrx ./Zulip-5.11.1-x86_64.AppImage 
> ./Zulip-5.11.1-x86_64.AppImage 
[67088:0928/120758.497901:FATAL:setuid_sandbox_host.cc(163)] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that /tmp/.mount_Zulip-aqQ8fJ/chrome-sandbox is owned by root and has mode 4755.
Trace/breakpoint trap (core dumped)

Expected behavior

Zulip should open

Screenshots

NA

Desktop (please complete the following information):

• Operating System: Ubuntu 24.04.1 LTS x86_64 (Wayland)
• Zulip Desktop Version: 5.11.1-x86_64

Additional context

This issue has previously been seen before #912.

This works fine with --no-sandbox.

This is a different issue that affects all Electron AppImage applications on Ubuntu 24.04; see

• [Bug]: The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. electron/electron#42510

You can try the sysctl change described in that thread (more information), but my suggestion would be to use one of our other package formats (deb, Snap, or Flatpak).

Right, will close this then, since it's not relevant.
