Traekik v2 latest : exec / operation not permitted

Hi, I'm new with traefik and use Docker Compose Traefik v2 - Easy Walkthrough - Updated 2024 ( as tutorial for the begining.
The systeme is ubuntu Linux docker 5.15.0-91-generic #101-Ubuntu SMP Tue Nov 14 13:30:08 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

I have followed al steps and when runing the container I get the following error in the log for traefik and portainer. Any ideas ?

exec / operation not permitted
exec /portainer: operation not permitted

Are you running Docker root-less?

I launch docker with root account.

If Traefik and Portainer are not working, than its rather a Docker problem. Docker has their own forum, check there (link).

It's probably a permission issue with user/files or because of SELinux/AppArmor restrictions.
