Title:
  Upgrading to Xenial leaves empty /usr/lib/x86_64-linux-gnu/pango/
  hierarchy

Status in pango1.0 package in Ubuntu:
  New

Bug description:
  During an upgrade from a Trusty system to Xenial, I ended up with the
  following problem:

  Removing linux-image-extra-3.13.0-85-generic (3.13.0-85.129) ...
  depmod: FATAL: could not load /boot/System.map-3.13.0-85-generic: No such file or directory

  Errors were encountered while processing:
   linux-image-extra-3.13.0-85-generic
  E: Sub-process /usr/bin/dpkg returned an error code (1)

  Turns out this was directly caused by simplistic checking in the
  plymouth initramfs-tools hook:

                  # wheezy
                  if ls /usr/lib/x86_64-linux-gnu/pango/1* > /dev/null 2>&1

  I want back and checked a backup of my original Trusty filesystem, and
  it indeed has an empty hierarchy here:

    kiko at gasolinux:/usr/lib/x86_64-linux-gnu/pango$ ls -lR
    .:
    total 4
    drwxr-xr-x 3 root root 4096 Feb 26  2014 1.6.0/

    ./1.6.0:
    total 4
    drwxr-xr-x 2 root root 4096 Feb 27  2014 modules/

    ./1.6.0/modules:
    total 0

  This may be better handled by smarter code in the plymouth hook, or if
  the empty directory may have further consequences, by making the pango
  upgrade really clean up that directory.

  I solved the problem by removing the hierarchy and re-running apt-get
  -f install.
