Title:
  free space need for /usr could be negative which is wrong

Status in ubuntu-release-upgrader package in Ubuntu:
  In Progress

Bug description:
  In my case I ran out of diskspace in /usr which required a temporary 4
  GB of more data during upgrade. Things just start to fail, and I can
  tell you - then you are screwed. I find this unacceptable for a wide-
  spread official LTS upgrader.
