Hello Jean-Baptiste, or anyone else affected,

Accepted ubiquity into trusty-proposed. The package will build now and
be available at https://launchpad.net/ubuntu/+source/ubiquity/2.18.8.9
in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation 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.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

  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
