        michael at isolde:~/my-hello-desc$ getfacl
        bash: getfacl: command not found
        michael at isolde:~/my-hello-desc$ setfacl
        bash: setfacl: command not found
        michael at isolde:~/my-hello-desc$ whereis getfacl
        getfacl:
        michael at isolde:~/my-hello-desc$ whereis setfacl
        setfacl:
        michael at isolde:~/my-hello-desc$ which getfacl
        michael at isolde:~/my-hello-desc$ which setfacl
        

You tell me.  Perhaps you want to read that last subordinate clause in
that last sentence there that you quoted?  For your convenience I've
bolded it.  It's also worth noting that the acl package in Ubuntu is not
