[Bug 946663] Re: Installer stuck at "Removing conflicting operating system files..."

[bwat47]

I don't think this bug has anything to do with ntfs. This bug is very
easily reproducible with ONLY a separate ext4 home partition, and no
ntfs partitions at all. Quite a serious bug as keeping your home
partition unformatted so you don't need to wipe all your data (for
example I have 100+ gigs of music, thats a huge pia to have to copy over
every 6 months). Upgrading using distro upgrade can often be
problematic, so this is the best way to "clean install" and keep your
data, this is something that really needs to work on final release (not
to mention this bug also borks your previous install)

Title:
  Installer stuck at "Removing conflicting operating system files..."

Status in “ubiquity” package in Ubuntu:
  Confirmed

Bug description:
  This is happening to me in both Ubuntu and Xubuntu 12.04 alpha install
  CDs.

  I have several partitions but I choose only two: one as the root (/)
  dir which I choose for formatting, and one as /home without
  formatting. Both are marked as ext4.

  The installer formats the root partition and then it says "Removing
  conflicting  operating system files..." and it never leaves that
  state.

  Before running the installer, I install the "Broadcom STA wireless"
  drivers and enable my wifi connection.
