[Bug]: debian package : the app fails to start due to a permission issue

[wsourdeau]

Can you reproduce this bug in the PWA?

No

Describe the bug

/opt/teams-for-linux/chrome-sandbox is not setuid root (user) after installation

What package are you using?

deb

Version

1.12.6

Reproduction steps

1. install the debian package
2. start Teams

Expected Behavior

The /opt/teams-for-linux/chrome-sandbox would be both owned by root and have mode 4755.
Suggestion : the postinst script could execute "chmod 4755 /opt/teams-for-linux/chrome-sandbox".

Debug

Running teams shows the following message :

"[8062:0124/175501.605834:FATAL:setuid_sandbox_host.cc(163)] 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/teams-for-linux/chrome-sandbox is owned by root and has mode 4755.
"

Additional context

No response

I also got that error on a fresh Ubuntu 24.04 installation. Setting owner and modes as suggested by the error message made it work.

Thanks for reporting. This one is the same as #1426. Check the comments for a more permanent solution. You need to create an app armour profile.

This is a change by Ubuntu that electron and electron build have passed to the users. Hopefully they will find a nicer way to fix this.
