Bug description:
  Installer version: 20101020ubuntu500

  Kernel: 4.10.0-14

  Description/Reproduction:

  During installation, the installer finds LVM volume groups from a
  previous installation.

  Current LVM configuration:
   Unallocated physical volumes:
     * /dev/mapper/mpatha2                                  (21218MB)
                                                                              
   Volume groups:                                                       
     * rootVG                                               (21218MB)
       - Uses physical volume:         /dev/dasda2          (21315MB)
       - Uses physical volume:         /dev/mapper/mpathc1  (21470MB)
       - Uses physical volume:         [unknown]            (21470MB)
       - Uses physical volume:         [unknown]            (21470MB)
     * rootVG                                               (21470MB)
       - Uses physical volume:         /dev/dasda2          (21315MB)
       - Uses physical volume:         /dev/mapper/mpathc1  (21470MB)
       - Uses physical volume:         [unknown]            (21470MB)
       - Uses physical volume:         [unknown]            (21470MB)
     * rootvg                                               (42685MB)
       - Uses physical volume:         /dev/mapper/mpathb1  (21470MB)
       - Uses physical volume:         [unknown]            (214

  When trying to remove that LVM using "Configure the Logical Volume
  Manager", it is not possible to remove logical volumes. The error "The
  logical volume swapLV on rootVG could not be deleted." is displayed.
  In syslog, you see the following messages:

  Apr  3 12:55:56 partman-lvm:   Multiple VGs found with the same name: skipping rootVG
  Apr  3 12:55:56 partman-lvm:   Use --select vg_uuid=<uuid> in place of the VG name.

  As you cannot use the suggested parameter in the installer, the system
  cannot be installed without manually removing the LVM setup with
  another shell.

  Debug logs are attached
