Indeed it is a duplicate. The fix is just the hotfix I'd done myself if
having that problem.

I'll link the debian bug in a comment on the other bug.

Title:
  UnicodeDecodeError in checkFreeSpace on 13.10=>14.04 upgrade

Status in “update-manager” package in Ubuntu:
  New

Bug description:
  Steps:

   1. Use a locale that has an LC_NUMBER with a no-breaking space (or some other non-ascii character)
   2. Have too little space on one mount (for me it was /boot)
   3. Can't do release upgrade to 14.04 (well, not getting any error message)

  I sent a patch upstream[0], but I don't know if it'll be accepted, and
  also, this won't really help unless the package is updated on the
  versions people upgrade from.

  I suggest instead that you code around it in the trusty upgrade
  script. The offending line is the apt_pkg.size_to_str(). Instead of
  using that bare, you should prepend a `.decode('utf-8')` to it.

  I don't know where the code for that trusty tarball is held, so I
  don't have a patch. But I can do that if you tell me where. (should be
  a simple fix though).
