Title:
  'upgrading' from 32 bit to 64 bit leaves 32 bit kernel and grub
  options present

Status in “ubiquity” package in Ubuntu:
  Triaged

Bug description:
  I used a LiveCD to 'upgrade' my accidental 32 bit install to a 64 bit
  install.  On rebooting, selecting the default option in grub didn't
  boot but selecting the 'older versions' option in the menu and
  selecting the kernel presented there (actually exactly the same
  version) worked.  And looking in /boot, we see:

  mwhudson at narsil:~$ ls /boot
  abi-3.0.0-12-generic         initrd.img-3.0.0-12-generic      System.map-3.0.0-12-generic-pae
  abi-3.0.0-12-generic-pae     initrd.img-3.0.0-12-generic-pae  vmcoreinfo-3.0.0-12-generic
  config-3.0.0-12-generic      memtest86+.bin                   vmcoreinfo-3.0.0-12-generic-pae
  config-3.0.0-12-generic-pae  memtest86+_multiboot.bin         vmlinuz-3.0.0-12-generic
  grub                         System.map-3.0.0-12-generic      vmlinuz-3.0.0-12-generic-pae

  -- the 32 bit pae kernel is still hanging around.  dpkg doesn't think
  they belong to any package, but they are there.
