no prompt for password when upgrading packages

[Book 'em Dano]

A daemon works in the background to update the list of available and upgradeable packages, then update-manager pops up and displays which packages have upgrades available. When I click on the "Install Updates" button, update-manager proceeds to download and install the upgrades but before doing so, no window pops up to ask for a user's password before installing the packages. In previous releases, a window would pop up and prompt for the user's password before downloading and installing upgrades.

This is a video of update-manager displaying the new updates that are available. Once I click Install, update-manager does not prompt for my password and proceeds to download and install the updates.
