First encounter

To Reproduce

I only installed the new version and it failed. Unfortunately, I haven't tried the old version after system update.

A clear and concise description of the problem...

Expected behavior

The Luban should start :-)

🌍 Your Environment

Platform:

- Operating System: Ubuntu 24.04
- Printer:  Snapmaker A250

It's happening for me as well after upgrading to Ubuntu 24.04 LTS. I had Luban 4.12.0 installed which was working fine before upgrade. After ubuntu upgrade, I can confirm both 4.12.0 and 4.13.0 are not starting with the error:

:~$ snapmaker-luban LaunchProcess: failed to execvp: /opt/Snapmaker Trace/breakpoint trap [38282:0100/000000.684022:ERROR:zygote_linux.cc(646)] write: Broken pipe (32)

After some investigation I found out that it is most likely caused by this issue which is hitting several electron apps. It seems related to apparmor Unprivileged user namespace restrictions that are now enabled by default in Ubuntu 24.04

Disabling the sandbox makes Luban start: snapmaker-luban --no-sandbox --disable-gpu-sandbox

The problem is still present with Luban 4.15.0, luckily I just needed to add the --no-sandbox to work around it. Thanks @aiurlano !
