When I tried with "Download updates while installing" and "Use LVM", it failed twice.
When I opted not to download updates, it failed again.
When I opted not to download updates and didn't ask for LVM, it claimed success. I suspect this is an Ubuntu problem with UEFI; if so, it would be good to disable the LVM option on systems using UEFI and add a caption "Not compatible with host UEFI".
