Title:
  Ubiquity does't start, hangs in "/usr/lib/ubiquity/bin/ubiquity", line
  426, in acquire_lock, test_debconf.stdout.readline()

Status in “ubiquity” package in Ubuntu:
  Confirmed

Bug description:
  All flavors and archs of Utopic Desktop.
  Last known good image is 20140527.

  ubiquity-dm and ubiquity do not start.
  Ubiquity started from the command line hangs forever, interrupting with CTRL-C shows that it's waiting on:

  -----
  ubuntu at ubuntu:~$ ubiquity -d
  ^CTraceback (most recent call last):
    File "/usr/lib/ubiquity/bin/ubiquity", line 636, in <module>
      main(oem_config)
    File "/usr/lib/ubiquity/bin/ubiquity", line 546, in main
      acquire_lock()
    File "/usr/lib/ubiquity/bin/ubiquity", line 426, in acquire_lock
      test_debconf.stdout.readline()
  KeyboardInterrupt
  umount: /var/lib/polkit-1/localauthority/90-mandatory.d: not mounted
  ----

  The following command works fine from the command line
  echo "VERSION 2.0"|sudo debconf-communitate -fnoninteractive ubiquity
