Accepted ubuntu-release-upgrader into xenial-proposed. The package will
build now and be available at https://launchpad.net/ubuntu/+source

-proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

  Upgrade from xenial to yakkety fails due to a UnicodeDecodeError

  Fix Committed

Bug description:
  Test Case
  ---------
  1) Install the package shim-signed on an Ubuntu 14.04 system
  2) Run do-release-upgrade -f DistUpgradeViewNonInteractive
  3) Observe the following Traceback:

  Setting up shim-signed (1.18~16.04.1+0.8-0ubuntu2) ...
  find: Error in sys.excepthook:
  Traceback (most recent call last):
    File "/usr/lib/python3/dist-packages/apport_python_hook.py", line 63, in apport_excepthook
      from apport.fileutils import likely_packaged, get_recent_crashes
    File "/usr/lib/python3/dist-packages/apport/__init__.py", line 5, in <module>
      from apport.report import Report
    File "/usr/lib/python3/dist-packages/apport/report.py", line 15, in <module>
      import xml.dom, xml.dom.minidom
  ImportError: No module named 'xml.dom'

  With the version of ubuntu-release-upgrader from -proposed you will
  not encounter the Traceback.

  Regression Potential
  --------------------
  The change modifies the code so that errors are ignored when decoding output, so some messages may be less readable.  However, this is better than having the release upgrader crash and the upgrade fail.

  Original Description
  --------------------
  When doing an automated upgrade from xenial to yakkey, I get:
  Preparing to unpack .../policykit-1_0.105-16_amd64.deb ...
