Bug description:
  This is a bug report about errors during the upgrade process. I don't
  know whether or not my samba installation was working immediately
  before the upgrade; the windows box that was intended to be a client
  died and has not been replaced. Don't believe my answers to the forced
  questions.

  ***

  My ubuntu system locks up regularly. Bugs I've reported about this get
  closed for inattention, after being ignored, and queries about how to
  do basic debugging get the same treatment, so I just power cycle
  whenever it happens again.

  This time the lock up happened while the GUI upgrade-everything-to-
  latest tool was running.

  When I power cycled the box to recover, the system was unusable -
  flashing "system problem detected" popups, none staying stable long
  enough to respond.

  ssh + "sudo apt-get update" + "sudo apt-get upgrade" pointed me to
  "sudo dpkg --configure -a"

  That command reported numerous errors - I don't know which of them are
  "normal" for this system, but hidden by the GUI, and which are new.

  But it got the system semi-usable from the GUI, so now I'm clicking on
  "yes, report it" for the many pop-ups, of which this is one.

  FWIW, samba is one of the ones "dpkg --reconfigure -a" complained
  about.
