Title:
  ubiquity crashed with AttributeError in install(): No frontend
  available

Status in “ubiquity” package in Ubuntu:
  New

Bug description:
  Is running ubiquity from an installed machine  "allowed"?  Even if
  not, it shouldn't crash like this.

  Installed Lubuntu 11.10 Beta 1.  Updated to today ,using sudo apt-get
  update && sudo apt-get upgrade

  sudo apt-get install ubiquity

  At a (bash) shell prompt in LXTerminal, I typed the command

    ubiquity

  and it crashed, apparently unable to start the debconf front end?

  debconf itself is apparently working fine on this machine:

    sudo debconf-get samba-common/workgroup

  outputs WORKGROUP for example.


  $ lsb_release -rd
  Description:	Ubuntu oneiric (development branch)
  Release:	11.10
  $ dpkg-query -W ubiquity
  ubiquity	2.7.25
  $

  Expected behaviour: Ubiquity UI should appear
  Actual Behaviour: crashed.
