[Bug 1159589] Re: When applying software updates, updater window disappears

[Aere Greenway]

I just tried the Software Updater (Update Manager) on Lubuntu 12.10, on
my 450 megahertz machine, and for the first time, the window showing
packages being downloaded (and later updates being applied), appeared,
and did not go away, which is what I expected to happen.

With faster machines, the problem of this bug-report would sometimes
happen, and sometimes not.  So I don't know if the problem has been
fixed, or if it just got lucky this one time.  But this is the first
time I have ever seen it work on the 450 megahertz machine.

I also tried it on UbuntuStudio 12.04 (on the 450 megahertz machine),
but the problem was still evident there.  So if it is fixed in Lubuntu
12.10, that fix is not in UbuntuStudio 12.04.  I no longer have any
Lubuntu 12.04 machines, so I can't test it on that level of Lubuntu.

Title:
  When applying software updates, updater window disappears

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

Bug description:
  On slow machines (450 megahertz, with 512 megabytes RAM in this case),
  when you request to install the selected software updates, the system
  updater window disappears.  Yet updates are being installed in the
  background, invisible to the user.

  The only clue there is that this is happening, is if you watch what
  processes are executing, using the task manager.

  Eventually (after a very long time on this machine), the CPU usage
  goes down to an idle state, yet no notification of a reboot being
  necessary appears (though a new kernel was one of the updates).

  If at that point, I bring up the software updater, it then informs me
  that a reboot is required.

  Similar symptoms to this occur on Ubuntu-Studio (Xubuntu) 12.04,
  except that the update manager window stays visible, and eventually
  says that a reboot is required.

  I want to watch the update process.  I don't want it to happen in the
  background (with no notification that it is finished) - especially on
  this slow machine.

  This doesn't happen on any of my other machines running Lubuntu 12.10,
  or Ubuntu-Studio 12.04 LTS.
