 ### Ansible
 
 On Debian 11 the default version of `ansible` is 2.10.08 which fails to extract binaries for TUSd.
-- workaround: 
-  - `sudo vim /etc/apt/sources.list` add this line : `deb http://ppa.launchpad.net/ansible/ansible/ubuntu focal main`
+- workaround:
+  - because of Puppet, we need to create dedicated sources.list file for ansible
+  - `sudo vim /etc/apt/sources.list.d/ansible_ubuntu_focal_main.list` add this line : `deb http://ppa.launchpad.net/ansible/ansible/ubuntu focal main`
   - then `sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 93C4A3FD7BB9C367`
   - followed by `sudo apt-get update` and `sudo apt-get install ansible -y`
 - Note that you might need to `sudo apt remove ansible` `sudo apt autoremove` before you try to install ansible.
