[Bug 905442] Re: update-manager doesn't actually install updates

[Sam_]

Similar, except, here the window doesn't dim and usually update-manager pops up daily without user being interactive because it's set do so in dconf.
But since I need to do some testing for another bug 903271 I run apt-get update in a terminal (before update-manager appears in launcher automatically).
After update-manager pops up in launcher and opening it, it lists e.g. the new kernel 3.2.0-5, which requires authentication to install.
Click on install button brings up authentication dialog window, insert password and press 'enter' key, dialog window closes and nothing happens, the list of updates is still there.
Disappearing authentication dialog window happens reproducable when new packages require authentication.
Upgrade via terminal works throughout perfectly.

Title:
  update-manager doesn't actually install updates

Status in “update-manager” package in Ubuntu:
  Confirmed

Bug description:
  I manually open update-manager, it shows a bunch of updates available,
  I hit "Install Updates", it asks me for my password, then stalls for
  about six seconds before ungreying, showing the same updates. It never
  does actually install the updates. apt-get upgrade works fine.

  It's kinda... impossible... to test this on a fully updated system, so
  no, I'm a bit short on the updates. Let me know if something changed
  recently that might fix this.

  update-manager also never starts on its own -- I have to manually
  start it. Let me know if this is a separate bug or not.
