Title:
  Unbuntu 11.04 installer crash - occured after configuration when
  removing packages

Status in “ubiquity” package in Ubuntu:
  New

Bug description:
  Binary package hint: ubiquity

  1) Bug affects "Ubuntu 11.04 - the Natty Narwhal".

  2) Ubuntu Software Center 4.0

  3) Expected Ubuntu 11.04 to install to completion and provide a clear
  signal that the installation completed successfully.

  4) Installer crashed prior to installation completion.

  Don't know how to attach more than one attachment in the initial bug
  report, so I plan to attach /var/log/partman as a follow up comment to
  this bug.
