I have two users in linux mint 18.02 xfce: adm - sudoer,  and user (desktop user) that is not sudoer.When starting gparted or users and groups from user - adm password is asked: Autentification as super user us required to perform that action.When starting software manager (mintinstall):  enter Your password to perform administrative tasks  is displayed - so I could not use it from user account. Is it possible to set software manager to ask for super user password, like gparted do, like it is in xubuntu?
How to set mintinstall to prompt for super user password from non sudoer account?
