套件： policykit-desktop-privileges (0.20ubuntu18.04.1)

run common desktop actions without password

This package provides a set of PolicyKit privileges which allow Administrators to run common actions without being asked for their password:

 * mounting and checking internal disk drives (through udisks)
 * setting the CPU speed and policy (through the GNOME CPU frequency applet)
 * setting the time and timezone (through the GNOME clock applet or through
   KDE)
 * Adding/changing system-wide NetworkManager connections
 * Update already installed software
 * Configure printers

It does not change privileges for non-Administrators (users who are not in the "admin" or "sudo" group). So this satisfies the typical desktop/laptop use case where the user has full control over the hardware anyway.

This is implemented by shipping a pklocalauthority(8) file.
