My theory on different versions of GRUB causing the issue didn't pan out. After wiping the PReP partition I was able to go between 14.04, 16.04, and 18.04 with no problems. The only way I've been able to reproduce the issue after fixing it is by filling the PReP partition with garbage using

$ dd if=/dev/urandom of=/dev/sda1

This may of happened in our CI by running a destructive storage test(badblock-destructive, fio).

@Scott MAAS is already telling Curtin to wipe the PReP partition, Curtin isn't fully wiping it which is why we're seeing the problem. I was merely suggesting wiping PReP by default may be useful in non-MAAS environments to prevent this error. I see why you wouldn't want to do that so feel free to ignore my suggestion :)
