[Bug 108351] update-manager should suggest how to retry

[Stephan]

You have been subscribed to a public bug:

Binary package hint: update-manager

After I was bitten by bug #107858 during an upgrade edgy->feisty 
the update manager gives no hint on how to retry.

If the upgrade was started via the panel icon the user does
not know the command to invoke the upgrade (after correcting an error).

Thus the message to the user is: "you've missed your chance to upgrade".

(button Report Bug doesn't work at this stage -- konqueror is trying to start
but no window shows up)
