I MAAS deployed an impacted system w/ the attached preseed to include your PPA, and curtin successfully installed. Afterward, the system entered a deploy loop, but there's no sign that this was related to your fix - rather, it may just be a boot order issue. Interrupting the loop and telling it to boot from disk caused it to successfully reach deployed state.
