I get the following error:

student@ubuntu:~$ lxc-start -n unpriv-cont-user -F

Welcome to Ubuntu 20.04.6 LTS!

Set hostname to .
Failed to create /init.scope control group: Permission denied
Failed to allocate manager object: Permission denied
[!!!!!!] Failed to allocate manager object.

The host is a cloud VM, it was created like in the first chapter it was detailed.
What do I missing? Why is it not starting the container?

    Nevermind...get back to it next day and it is working.
    I checked the previous steps if I missed to create anything but nothing missed. The only difference was just that for the setfacl command today I get a lot of "Operation not permitted" lines. Other than that everything was in place.
    The container is running, I continue the lab.
