where can I submit an errata?

Hi, I started solving exercises from one of the courses and found errors in the exercise descriptions along the way, where can I submit an errata? It's not something that can't be fixed, but perhaps for novice users it could be a hassle.

There is also a difference in the content of the pdf file with the exercises, if you open the one divided into parts, comparing with the large pdf file that contains all the exercises.

In the Lab 3.2 from the short file, you can read:

In order to prevent a possible permission error, we need to set an access control list on our
~/.local
directory. Using the same UID value extracted earlier from the
/etc/subuid
file, run the following
command:
student@ubuntu:~$ setfacl -R -m u:231072:x ~/.local

But in the descripiton from the longer file there is something like:

Reboot your host, or log out and then log back in:
student@ubuntu:~$ sudo reboot

In order to prevent a possible permission error, we need to set an access control list on our ~/.local
directory. Using the same UID value extracted earlier from the /etc/subuid file, run the following
command:
student@ubuntu:~$ setfacl -R -m u:231072:x ~/.local

But, there is no acl package in ubuntu by default, neither .local folder in $HOME after installation. So probably docs should be updated to avoid confusion. Nothing serious, but earlier commands were given for setting up individual directories and installing the packages needed in the next steps, so for the sake of consistency this can be added.

For completeness this section should precede:

Install acl package: $ sudo apt install -y acl and create a directory: $ mkdir ~/.local

Cheers
