Title:
  update-manager says "your computer is up-to-date" whereas there are
  still 48 packages to be upgraded

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

Bug description:
  - I run the update-indicator applet, which notifies me this morning that I have 51 updates to install. I run the "Execute" command which ends up installing Firefox only and saying "your computer is up-to-date", whereas the indicator still indicates 48 updates to install. 
  - Trying the "Execute" command again does nothing. 
  - Executing the update-manager command-line does nothing, still says "your computer is up-to-date"
  - Running synaptic and selecting "Mark all updates" installs the 48 lacking updates...

  Worked like a charm until last week.
