Issues Running AppImage Files on Lubuntu: SUID Sandbox Helper Binary Error

Lubuntu Support

Dear Lubuntu Community,

I am encountering difficulties when attempting to execute AppImage files on my Lubuntu system. Each time I run an AppImage, I receive the following error message:

[2174:1223/002851.683708: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_hydralPOzCKm/chrome-sandbox is owned by root and has mode 4755.
Trace/breakpoint trap (core dumped)

Despite these efforts, the problem remains unresolved. I am seeking guidance from the community on how to properly configure the SUID sandbox helper binary or any alternative solutions to successfully run AppImage files on my Lubuntu system.

  • OS: Lubuntu 24.04.1 LTS
  • Kernel Version: 6.8.0-51-generic
  • AppImage in Question: hydra-launcher-3.0.8.AppImage

I won’t offer advice, as my knowledge/experience with AppImages is limited, but I wonder if your issue relates to AppArmor changes that occurred with noble (24.04).

I’ll provide a link - https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/2046844
