[Bug 1540591] Re: fontconfig breaks Trusty - Xenial upgrade

[Launchpad Bug Tracker]

This bug was fixed in the package fontconfig - 2.11.1-0ubuntu8

---------------
fontconfig (2.11.1-0ubuntu8) xenial; urgency=medium

  * Make things depend on ≥ version-of-libfontconfig1-they-were-built-with, so
    that on new releases the library is upgraded before its rdeps. (LP:
    #1540591)

Title:
  fontconfig breaks Trusty - Xenial upgrade

Status in fontconfig package in Ubuntu:
  Fix Released
Status in fontconfig source package in Xenial:
  Fix Released

Bug description:
  Attempting to upgrade a fully updated 14.04.3 system to Xenial using
  the do-release-upgrade tool.

  The upgrade proceeds until it attempts to install fontconfig.  This
  fails and causes a cascading set of failures for 160+ more packages
  resulting in a system that boots, and has console access, but no
  Unity, and other things that either fail to work or only work halfway.

  Attempts after the failed upgrade to fix the issues via "apt-get -f
  install" fail with the same errors as seen during the upgrade.

  Here's the apt term log showing the errors, starting with fontconfig:

  And here's the contents of fontconfig.log as suggested by trying to
  manually install fontconfig vai "apt-get install fontconfig"
