[Bug 1350310] Re: update-manager chashes on 12.04.4 HWE update

[Paul Crawford]

Just to say a recent update has fixed this. There are still problems
with Nvidia driver post-update, but that is another bug...

Title:
  update-manager chashes on 12.04.4 HWE update

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

Bug description:
  In spite of apparent fixes for [bug #1342424] I find that the update-
  manager is still crashing and failing to perform the HWE upgrade to
  move my 12.04.4 LTS installation.

  If I run the update-manager from the command line I get the same
  behaviour as the normal alert when updates are availabe, but also
  additional information. It proceds correctly until it has asked for
  the sudoer password, then it prints the error messages and triggers a
  crash report.

  $ /usr/bin/update-manager
  Traceback (most recent call last):
    File "/usr/lib/python2.7/dist-packages/defer/__init__.py", line 473, in _inline_callbacks
      result = gen.throw(result.type, result.value, result.traceback)
    File "/usr/lib/python2.7/dist-packages/UpdateManager/backend/InstallBackendAptdaemon.py", line 54, in commit
      yield self._run_in_dialog(trans, self.INSTALL)
    File "/usr/lib/python2.7/dist-packages/defer/__init__.py", line 473, in _inline_callbacks
      result = gen.throw(result.type, result.value, result.traceback)
    File "/usr/lib/python2.7/dist-packages/UpdateManager/backend/InstallBackendAptdaemon.py", line 75, in _run_in_dialog
      yield dia.run()
  aptdaemon.errors.TransactionFailed: Transaction failed: None
   The following packages have unmet dependencies:

  libgl1-mesa-glx-lts-trusty: Depends: libglapi-mesa-lts-trusty (= 10.1.3-0ubuntu0.1~precise1) but 10.1.3-0ubuntu0.1~precise1 is to be installed
                              Depends: libx11-6 (>= 2:1.4.99.1) but 2:1.4.99.1-0ubuntu2.2 is to be installed
                              Depends: libxdamage1 (>= 1:1.1) but 1:1.1.3-2build1 is to be installed
  xserver-xorg-lts-trusty: Depends: xserver-xorg-core-lts-trusty (>= 2:1.11) but 2:1.15.1-0ubuntu2~precise1 is to be installed

  What I expect is the system to (A) correctly resolve and install the
  dependancies to get the HWE update, and (B) if it can't do that to not
  crash out when reporting the cause.

  Other systems details are:
