policykit-1 binary package in openKylin Yangtze V1.0 amd64

 polkit is an application-level toolkit for defining and handling the policy
 that allows unprivileged processes to speak to privileged processes.
 It was previously named PolicyKit.
 .
 This transitional package depends on polkitd, the system service used by
 polkit, and pkexec, a setuid program analogous to sudo. They were
 historically packaged together, but have been separated so that users of
 polkitd are not required to install pkexec.
