Ignore my last comment; I had chosen manual partitioning and it turns out that ubiquity is just extraordinarily unfriendly when it comes to EFI installations. Specifically, it didn't warn me it would completely fail if I didn't create an ESP partition, instead crashing spectacularly and supplying no useful information about what the problem might be ten minutes later when it got round to trying to install grub.
