Short reproducer:

$ lxc init ubuntu:focal/armhf focal-test
Creating focal-test
$ lxc start focal-test
$ lxc exec focal-test /bin/bash
root@focal-test:~# systemctl is-system-running
degraded

With some further diagnostics:
root@focal-test:~# systemctl list-units | grep failed
● systemd-remount-fs.service              loaded failed failed    Remount Root and Kernel File Systems
root@focal-test:~# systemctl status systemd-remount-fs

And the /etc/fstab file for posterity:
root@focal-test:~# cat /etc/fstab

Looks like this is an issue with the focal lxc image, nothing to do with
autopkgtest.

  focal armhf instances boot in degraded state

Bug description:
  Looks like Focal armhf instances boot in degraded state because the
  following systemd unit fails:

  root@paride-test:~# systemctl status systemd-remount-fs.service
  ● systemd-remount-fs.service - Remount Root and Kernel File Systems
       Loaded: loaded (/lib/systemd/system/systemd-remount-fs.service; enabled-runtime; vendor preset: enabled)

  Warning: journal has been rotated since unit was started, output may be incomplete.

  We should figure out why this happens, and make instances boot again
  in 'running' state.
