Which docs are you referring to? Your info is not here:

https://join-lemmy.org/docs/en/administration/install_ansible.html

Nor here:

https://github.com/LemmyNet/lemmy-ansible

Maybe the problem is this:

https://lemmy.ml/post/79861

Are trying to install Lemmy (executing Ansible) from the server where Lemmy will been working?

Really? I don't think so... There are some exceptions, like the use of Linux on secondary schools (12-18 years old): #Lincat http://linkat.xtec.cat/portal/index.php and others
