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

[Mark Fortescue]

Installation now totally bust - will have to revert to LTS 10.04 backup
and start again - another 16 hours of pain.

Key Failures:

As a release upgrade procedure - d0-release-ubgrade from LTS-12.04 to
14.04 is fundamentally broken as it corrupts the system irrecoverably
unless you un-install an un-known quantity of packages that it can't
hack before you start.

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

Status in ubuntu-release-upgrader package in Ubuntu:

  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.

  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.
