Title:
  Top-level checkbox only reverses selection, doesn't turn on/off

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

Bug description:
  To verify this bug, sign up for a PPA with several new packages. A
  random example is https://launchpad.net/~aapo-
  rantalainen/+archive/gcompris . Before installing the PPA, install
  gcompris and several language packs. Then install the PPA and refresh
  your apt cache.

  1. Open Update Manager and notice that the gcompris PPA section has several packages available.
  2. Uncheck one of the packages.
  3. Click the top-level checkbox for the PPA.
  4. Instead of deselecting everything in the PPA, the selection is reversed (what was checked is now unchecked and so on). And unchecking the PPA checkbox reverses the reversal.

  ========
  The checkbox is unchecked by default. Clicking the header checkbox makes everything on the page checked including the checkbox. Unchecking one of the items changes the header checkbox into a "checked but inconsistent status" which is represented by showing the checkbox checked but at ~50% of normal intensity. Clicking the header checkbox again unchecks everything. Checking a few items afterwards does not put the header checkbox into checked or inconsistent mode.

  GTK has an inconsistent mode but it doesn't seem to work the same way
  for checkboxes (it ought to!) and so doesn't seem to help:

  toggle-button-set-inconsistent

  
  What should happen:
  ===================
  1. All items should be checked by default.
  2. Unchecking an item should keep the header checked (if GTK properly represents the 3rd state, inconsistent, then that should be used now)
  2b. If all section items are manually unchecked then the section header should be unchecked too to match.
  3. Clicking the section header when it is in checked or inconsistent state and when some or all items are checked should uncheck all items including the section header.
  4. Checking an item should keep the header unchecked until all items are checked when the section header should be checked too to match.
  5. Clicking the section header when it is in unchecked state should make all section items checked.
