Crash after upgrading to Ubuntu 24.04

Description

jlab .
[514889:0921/151946.918521: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 /opt/JupyterLab/chrome-sandbox is owned by root and has mode 4755.
Trace/breakpoint trap (core dumped)

Reproduce

1. Install JupyterLab Desktop on Ubuntu 23.10
2. It works
3. Update to Ubuntu 24.04
4. It does not work

Expected behavior

Works

Context

• Operating System and version: Ubuntu 24.04
• JupyterLab-Desktop version: 4.2.5
• Installer: snap actually not sure

Looks related to electron/electron#42510 (comment) which contains a workaround - I can confirm that disabling kernel.apparmor_restrict_unprivileged_userns does work. I will try to reinstall with a snap package now.

Also, a safer workaround:

jlab .  --no-sandbox

as this only removes sandbox for jlab rather than disabling it globally.
