The error in the log is:

dpkg: cycle found while processing triggers:
 chain of packages whose triggers are or may be responsible:
  gconf2 -> gconf2
 packages' pending triggers which are or may be unresolvable:
  dbus: /etc/dbus-1/system.d
  resolvconf: resolvconf-enable-updates
  man-db: /usr/share/man
  systemd: /etc/init.d
  doc-base: /usr/share/doc-base
  libc-bin: ldconfig
  initramfs-tools: update-initramfs
  desktop-file-utils: /usr/share/applications
  ureadahead: /etc/init: /etc/init.d
  gconf2: /usr/share/GConf/gsettings: /usr/share/gconf/schemas
  php5-fpm: /etc/php5/fpm/conf.d

This points to a problem with the trigger in gconf2.
