Bug#964289: systemd-container: armhf countainer cannot be started on amd64 host

[Ryutaroh Matsumoto]

Package: systemd-container
Version: 245.6-1
Severity: normal

Dear Maintainer,

I installed
# dpkg-query -W | grep qemu-user-static
qemu-user-static	1:5.0-5

Then I built a root directory as

# mmdebstrap --components="main contrib non-free" --architectures=armhf --variant=important bullseye /var/lib/machines/armhf-bullseye

Then 
# systemd-nspawn -D /var/lib/machines/armhf-bullseye -a
works fine.

But I got the following error and could not start the container...
# systemd-nspawn -D /var/lib/machines/armhf-bullseye   -b
Spawning container armhf-bullseye on /var/lib/machines/armhf-bullseye.
Press ^] three times within 1s to kill container.
