Title:
  update incorrectly assesses free space in /usr

Status in update-manager package in Ubuntu:
  Invalid

Bug description:
  When trying to update the kernel group of packages (i.e. kernel,
  headers, etc.) update-manager stops and tells me:

  The upgrade needs a total of 263 M free space on disk '/usr'. Please
  free at least an additional 88.9 M of disk space on '/usr'. Empty your
  trash and remove temporary packages of former installations using
  'sudo apt-get clean'.

  But since we know that the only package that's going to want space in
  "/usr" is the kernel-headers and since we know the kernel-headers
  package actually wants space in /usr/src, we can determine that
  update-manager is incorrectly assuming /usr/src/ is in /usr.  /usr/src
  here has lots of room for another kernel-headers package:

  $ df -h /usr /usr/src
  Filesystem            Size  Used Avail Use% Mounted on
  /dev/mapper/rootvol-ubuntu_usr
                        9.9G  9.2G  166M  99% /usr
  linux:/usr/src         85G   80G  735M 100% /usr/src

  I'm sure if /usr/src had GBs free the complaint would still be the
  same since we can see that 735M is well clear of 263M.

  Sure enough, I freed space in /usr:

  
  $ df -h /usr /usr/src
  Filesystem            Size  Used Avail Use% Mounted on
  /dev/mapper/rootvol-ubuntu_usr
                        9.9G  9.1G  341M  97% /usr
  linux:/usr/src         85G   80G  735M 100% /usr/src

  and the update proceeded.

  So, update manager assuming that /usr/src == /usr is bad and broken.
