The .AppImage file fails to start without --no-sandbox flag.
At the very start I got this error message:
[119857:0409/130412.415857:FATAL:setuid_sandbox_host.cc(158)] 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_LDtk_OFFiq9K/chrome-sandbox is owned by root and has mode 4755.
Trace/breakpoint trap (core dumped)
From different apps I tried to unpack the app, add the required permissions to the chome-sandbox and repack it using appimagetool
After running the repacked version I got different error:
The setuid sandbox is not running as root. Common causes:
* An unprivileged process using ptrace on it, like a debugger.
* A parent process set prctl(PR_SET_NO_NEW_PRIVS, ...)
Failed to move to new namespace: PID namespaces supported, Network namespace supported, but failed: errno = Operation not permitted
Trace/breakpoint trap (core dumped)
At this point my limited skills are at the end and I did not managed to find solution towards this issue and creating an Issue about this.
