Hi David, Sorry about the late reply. I just got back on testing that utilizes the Debian QEMU chroot's.
Also note that this might be better assigned to qemu-user static (my apologies if it was mis-classified): $ sudo update-binfmts --display ... interpreter = /usr/bin/qemu-s390x-static ... package = qemu-user-static > It would be nice if you could provide a complete set of steps to > reproduce this, preferably starting with the setup of the chroot itself.
