Have you tried running a graphical agent? For example, lxpolkit
, polkit-gnome-authentication-agent-1
, or polkit-kde-authentication-agent-1
.
Alternatively, you could write a polkit rule that would remove the authentication requirement, either for a specific user or for 'wheel' members.
(Note that 'adm' does not normally mean "administrative privileges"; it means access to system logs and accounting data.)
