Got every setup to halium-install -p ut <rootfs.tar.gz> <system.img>
Unfortunately the install-script fires:

I tried it under macOS and Ubuntu 20.04 (in docker container). I also swapped between the standalone script and the full master branch but the error kept showing up.

I appreciate the project you guys are running here, I'd love to see UB Touch on my spare Nexus 6P,

Thanks you, Hannes
