Bug: AppImage Linux Ubuntu 24.04 LTS dosn't work

[kpietrzyk]

Is this an issue specifically with Appium Inspector?

• I have verified that my issue does not occur with Appium, and should be investigated as an Appium Inspector issue

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

after downloading and changing chmod of appimage i get this error:

[19889:0723/183728.430148: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_Appium5UZNUQ/chrome-sandbox is owned by root and has mode 4755.

There is no chrome-sandbox in that location so there is no way to change it's owner.

Same error after extracting tar files and changing chrome-sandbox ownership and mode.

Expected Behavior

Run Appium Inspector from command line AppImage

Operating System

Linux

Appium Inspector Version

2024.6.1

Appium Version

2.11.2

./appium-inspector --no-sandbox returns that:

I'm afraid we don't really have a Linux machine to test this ourselves, but I do have a few suggestions:

• Are you using the version that matches your computer architecture? (x64 or arm64)
• Does this error still appear on previous app versions? Note that if you're using arm64, support for it was only added in version 2024.3.4.

This is because Ubuntu restricted access to userns with apparmor

Linux mint rolled back that change

While solus dropped apparmor and snap support

Nice. Right after the fresh install, they made this kind of change :D Thank you for your support

1. Yes. I'm running x64 app on AMD Ryzen 5 3600X CPU
2. Yes. I tried to run previous version and the problem still occurred.

btw just in case there is no solution, if --no-sandbox doesn't work you will have to disable the restriction that ubuntu put in place.

sudo sysctl -w kernel.apparmor_restrict_unprivileged_unconfined=0
sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0

Thanks for the info @Samueru-sama!
