I think apport should suggest using other ways to upgrade. I created bug
423884 in this intent, so I'm marking this bug as a duplicate of it.

apport
Apport refuses to report bug if there are any updates available. You can
use synaptic package manager to update or use command line program like
apt-get
$ sudo apt-get update
$ sudo apt-get upgrade
** Package changed: ubuntu = update-manager (Ubuntu)
