Failure trying to run: chroot "/pi-gen/work/first_test/stage0/rootfs" /bin/true

I'm trying out pi-gen for the first time, and starting with the simplest config, but get chroot error.

Reproduce with:

pi-gen$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 20.04.5 LTS
Release:        20.04

pi-gen$ git log -1

pi-gen$ cat config 
IMG_NAME=first_test

I don't use docker myself, but I think the issue here is that you need to have qemu-user-static installed on the host system.

Installing qemu-user-static fixed it. Thanks!
