Title:
  calculation of needed free space in /boot is inaccurate and causes
  refusal to upgrade

Status in ubuntu-release-upgrader package in Ubuntu:
  New
Status in update-manager package in Ubuntu:
  New

Bug description:
  I have a /boot partition which is sized just right to accommodate 3
  kernels, plus a little bit of overhead.

  $ df -h /boot/
  Filesystem      Size  Used Avail Use% Mounted on
  /dev/sda5       280M  144M  118M  56% /boot
  $

  Previously, update-manager had no problem letting me upgrade kernels.
  With the latest kernel update in 16.10, I got an error message that I
  needed more free space on this filesystem.

  After bypassing update-manager with 'sudo apt dist-upgrade', the
  filesystem's usage looks like this:

  $ df -h /boot/
  Filesystem      Size  Used Avail Use% Mounted on
  /dev/sda5       280M  206M   56M  79% /boot
  $

  So update-manager is getting the disk usage requirement for /boot off
  by a factor of 2 (at least? I didn't save the error message from the
  dialog).

  It's better to refuse to upgrade than to fail mid-upgrade due to disk
  space, but not if that means getting stuck forever with an old kernel
  unnecessarily.
