as i understand this shall be executed by an administrator on the clients, but without root sudo, the commands are unsuccessful.
also on line 97, the `${uname}:${uname}` makes sense on most single user systems, but on a working enviroment, where multiple people login on a PC via ldap, by default users are on in the group, named the same as the username.......so that breaks as well but did no change it...yet, for me `${uname}:sudo` worked
(tried on ubuntu 20)
