Live Build error for Chromebook Veyron

Trying to build an iso for my Asus C100p flip as despite the hardware working perfectly Google have deemed it EOL as far as updates go.

Have been following the guide here: https://www.kali.org/docs/arm/kali-l...romebook-flip/ and the gitlab README: https://gitlab.com/kalilinux/build-scripts/kali-arm. I've set the chromebook into developer mode fine but am struggling to build the iso properly.

run build deps fine. When I run the actual script to build the iso (chromebook-arm-veyron.sh) it builds the directory and runs for ages before just stopping at a root prompt just after the python2 prompt from the kali devs. I've tried running this in my kali VM a couple of times and even installed kali to bare metal on old laptop to try it there but same problem.

Not sure what I'm doing wrong here but any help would be great! TIA! see screenshot at point of failure(feel free to lol at my futile attempts to make it continue)Attachment 4615
