Interestingly, last night I downloaded a snappy core image, but that also refused to boot.

I find that very interesting indeed. Out of interest what is the exact model of your Pi?

The correct image is indeed:

https://download.nextcloud.com/server/images/ubuntu-standard-16.04-server-armhf-rpi2-installer-20161018.img.zip

from:

Nextcloud Box OS images

Here are the images we can share with the public and that you can flash on a Nextcloud Box. Pi2 Image-20161018 MD5 SHA256 Pi3 Images have been delayed until January Flashing guide

Here is a SO link talking about rainbow screen, it may be that adding the delay to your config file will resolve it.

Raspberry Pi with boots up with Rainbow screen

Other than that I’m unsure what to suggest really, this image is known to work with the Pi2, and is the official version of the image I was providing before that to over 50 downloads confirmed as working.
