SocialStream.ninja AppImage Sandbox Error Fix

Problem

When running the SocialStream.ninja AppImage, users may encounter this error:

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_socialRwnnm/chrome-sandbox is owned by root and has mode 4755.

Solution

Create an AppArmor profile to allow the application to run with unprivileged namespaces:

  1. Create a file at /etc/apparmor.d/obsidianappimage (or appropriate name for your app) with: ```

    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 obsidianappimage /path/to/YourAppImage flags=(default_allow) { userns,

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


2. Replace `/path/to/YourAppImage` with the actual path to your AppImage file

3. Save the file and run:

sudo systemctl reload apparmor.service ```

  1. If that doesn’t work, reboot your system

This solution allows AppImages that use Chrome/Electron to run without SUID sandbox configuration issues on systems with restricted user namespaces.
