[Bug 1045285] Re: lucid upgrade to precise fails (lxdm: subprocess installed post-installation script returned error exit status 1)

[Dave Howorth]

Thanks for the suggestion. I have made that change to
/var/lib/dpkg/info/lxdm.postinst (note - NOT lightdm's postinst - I
can't find that in /var/lib/dpkg/info/).

I wasn't certain what I was supposed to do next, so I then tried "dpkg
--configure -a" again. It failed again and I attach its log. Please let
me know if I should have tried something else.

Bug description:
  I tried to upgrade a machine from 10.04 to 12.04. It failed with
  symptoms similar to those described in

  https://bugs.launchpad.net/ubuntu/+source/python-defaults/+bug/990740

  but following guidance there, I am opening my own report to avoid
  mixing symptoms of possibly different bugs. I'm new to the whole
  launchpad process so please be gentle. I tried to use ubuntu-bug to
  report the bug, but it failed, so I'm reporting manually:

  $ ubuntu-bug update-manager
  Traceback (most recent call last):
    File "/usr/share/apport/apport-gtk", line 15, in <module>
      from apport import unicode_gettext as _
    File "/usr/lib/python2.6/dist-packages/apport/__init__.py", line 1, in <module>
      from apport.report import Report
    File "/usr/lib/python2.6/dist-packages/apport/report.py", line 18, in <module>    from problem_report import ProblemReport
  ImportError: No module named problem_report

  More in the next post if this works ...
