Public bug reported: Partition setup was a luks partition with an existing home directory, which I'd unlocked prior to starting ubiquity (otherwise it wouldn't even find the partition)
Bootloader install partition was an efi system partition This section of syslog looks relevant, looks like it couldn't handle the encrypted disk Apr 11 10:02:32 kubuntu ubiquity: grub-install: error: attempt to install to encrypted disk without cryptodisk enabled.
