[Bug 878568] Re: Ubiquity's Installation Type Window Totally Unresponsive

[SlugiusRex]

The issue is related to the fact that the drive is descried as "Raid
Component" in the Disk Utility Image (see comment #2).

I was able to use disk utility to remove this by formatting the drive as
empty ~ and was able to continue on with the installation.  So I am now
happy.  However I am very displeased with the installation process.  I
believe that this drive being flagged as "Raid Component" is what caused
the original 11.04 to 11.10 system upgrade to fail; and is also
responsible for the USB/DVD installation process to break.

All of the documentation I found on-line says that I should have first
seen a Ubiquity screen that displays some nice graphics offering the
"Install Alongside / Erase Disk / Something Else"  options.  But this
never happed.  Instead Ubiquity went straight to the  partition editor
screen ~ but that screen was missing the nicely colored partition
representation at the top of the screen.  Also, none of the buttons
worked ~ and the only option was to abandon the installation using quit.

The cause of the problem dates back to my initial installation of
Jaunty/Karmic on this machine.  At that time the default Windows
installation was ditched, and Ubuntu was successfully installed using
the pre-Ubiquity installer/partitioner.  However, during all the
subsequent Karmic -> Lucid -> Natty conversions the problem never
surfaced.

Ubiquity should provide a more more elegant for detecting that the
partitioner cannot proceed and should give a more useful approach to
continuing the installation instead of just forcing the Quit.

Title:
  Ubiquity's Installation Type Window Totally Unresponsive

Status in “ubiquity” package in Ubuntu:
  New

Bug description:
  Attempting to install 11.10 on a completely new unformatted disk

  Update manager completely mangled my previous 11.04 desktop and
  corrupted GRUB ~ so I deleted all the disk volumes, and am attempting
  to install fro scratch.

  The "trial" works great, and I am able to get as far as the
  "Installation Type" window.  However, at that point, none of the
  buttons are responsive; and 'Install Now' reports 'No root file system
  is defined.  Please correct this from the partitioning menu'.
