traceback when gathering dmi information

Could you give me some more information about the image you are using? I've been unable to recreate this.

This was a stock lxc launch.

$ lxc launch ubuntu-daily:bionic b4
$ lxc exec b4 /bin/bash
root@b4:~# cat /etc/cloud/build.info
build_name: server
serial: 20180411

root@b4:~# ubuntu-bug systemd
