Title:
  When Wubi is installed from CD, ubiquity crashes at the end of the
  installation

Status in Wubi, Windows Ubuntu Installer:
  Confirmed
Status in “apt” package in Ubuntu:
  New
Status in “ubiquity” package in Ubuntu:
  New

Bug description:
  Because of bug #207137 Wubi now copies the CD content as opposed to
  extract an ISO. This was implemented via bug #230716 which allows
  casper to boot off a directory. That directory is bindmounted to
  /cdrom in the initrd. But that makes ubiquity/install.py >
  install_extras > do_install > cache.commit fail, since apt/python-apt
  does not work correctly when /cdrom is bind-mounted.

  That in turn can be tracked down to fetcher.Run() in apt/cache.py

  cache.py > Cache.commit > Cache._fetchArchives >
  self._runFetcher(fetcher) > fetcher.Run()

  Where

  fetcher = apt_pkg.GetAcquire(fetchProgress) -> Acquire instance

  When installing Wubi from an ISO (no bindmount) or when setting up
  /cdrom via a symlink in casper, the installation proceeds correctly.
