[Bug 1505021] Re: do-release-ubgrade from 12.04 LTS to 14.04 LTS fails

[Brian Murray]

It'd be helpful if you were to provide the file /var/log/dist-upgrade
/apt-clone_system_state.tar.gz from the system, this way we can try and
investigate which packages the release upgrader "can't hack".

The files apt.log, apt-term.log and main.log from the same folder would
be even more helpful.

Title:
  do-release-ubgrade from 12.04 LTS to 14.04 LTS fails

Status in ubuntu-release-upgrader package in Ubuntu:
  Incomplete

Bug description:
  The command fails as shown:

  One of the causes is simply that my local setting is 'LANG=C' which is
  the default locale and must always be supported by the C library
  despite the messages given (it is the default so it must be supported
  !!!).

  Using 'LANG=enGB.utf8  sudo do-release-upgrade' gets further but I
  still get  python/gtk warnings that someone needs to sort out.

  gtk: gir1.2-gtk-2.0: Installed: 2.24.10-0ubuntu6.2
  python: Installed: 2.7.3-0ubuntu2.2

  The starting point was 10.04 LTS.  This was upgraded to 12.04.5 LTS
  and I am now trying to update to 14.04 LTS.
