tout de suite mieux...

  Confirmed

Bug description:
  If /etc/apt/sources.list or /etc/apt/sources.list.d/*.list files
  contain non-ASCII symbols in comments (like russian '# заблокировано
  при обновлении до precise') then do-release-upgrade fails with (was
  trying upgrade from 12.04 to 12.10 beta):

  Traceback (most recent call last):
