[Bug 2041831] Re: [SRU] Update-manager crashes when packages are de-selected with the mouse

[Nathan Teodosio]

In 24.04 virtual machine I installed 1:24.04.9,

I clicked various check boxes in the package list (i.e. unselect some
packages with the mouse), no crash happened; all normal.

I executed apt list --upgradable > before, left only Vim packages
checked in update-manager, and clicked install now.

After completion I did apt list --upgradable > after, update-manager
recalculated its view and indeed the Vim entries are now gone. 'diff
before after' is correct:

Title:
  [SRU] Update-manager crashes when packages are de-selected with the
  mouse

Status in update-manager package in Ubuntu:
  Fix Released
Status in update-manager source package in Noble:
  Fix Committed

Bug description:
  Impact
  ------

  Update-manager crashes if packages are deselected with a mouse click.
  If the keyboard spacebar is used instead (with focus on the package
  name or whole line, not the checkbox) it doesn't crash.

  Test case
  ---------

  0. Install the updated update-manager package.
  1. Start update-manager.
  2. Click various check boxes in the package list (i.e. unselect some packages with the mouse).

  Update-manager should not crash.

  Run the basic test plan in
  https://wiki.ubuntu.com/DesktopTeam/TestPlans/UpdateManager too.

  Regression potential
  --------------------

  The user interface could become unresponsive.
