You need to make sure that /snap/mqttx/x1/chrome-sandbox is owned by root and has mode 4755.

I have installed MQTTX 1.1.1 by snap file, but when i try to run it i get:

"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 /snap/mqttx/x1/chrome-sandbox is owned by root and has mode 4755.
Trace/breakpoint trap (core dumped)"

And, after try to:

sudo chmod 4755 /snap/mqttx/x1/chrome-sandbox

i get these same message. Can you help-me?

Hi, @XxKavosxX. Actually I haven't used sanp file for real installation, but I found some ways that might be useful to you.

CONFIG_USER_NS=y enables the user namespaces feature, but they're still restricted to privileged users by default. This suggests sysctl kernel.unprivileged_userns_clone=1

or

• sudo chown root chrome-sandbox
• chmod 4755 chrome-sandbox
