There are three more packages left in openSUSE:Factory that report
  polkit-untracked-privilege

Those packages were added to Factory AFTER the announcement that this will turn
into an error and are thus not included in the amnesty agreement.

Thus, please review the three packages (they all belong closely together):

* switchboard-plug-locale
  switchboard-plug-locale.x86_64: W: polkit-untracked-privilege
org.pantheon.switchboard.locale.administration (no:no:auth_admin_keep)

* switchboard-plug-security-privacy
  switchboard-plug-security-privacy.x86_64: W: polkit-untracked-privilege
org.pantheon.security-privacy (no:no:auth_admin_keep)

* switchboard-plug-useraccounts
  switchboard-plug-useraccounts.x86_64: W: polkit-untracked-privilege
org.pantheon.switchboard.user-accounts.administration (no:no:auth_admin_keep)
