Bug Description

When investigating a failed lxd-armhf worker unit I noticed the following in its log file:

The test being run was "Received request for package unattended-upgrades on kinetic/armhf; params: {'triggers': ['lsb-release-minimal/0.5-1'], 'submit-time': '2022-08-10 00:47:06'}" and that test did end up passing later - https://autopkgtest.ubuntu.com/results/autopkgtest-kinetic/kinetic/armhf/u/unattended-upgrades/20220810_021012_94612@/log.gz

By looking at the code this can happen if running

  lxc exec container_name -- cat /proc/uptime

fails (returns nonzero). If autopkgtest-virt-lxd believes the container is up but that command fails I think it's fair to bail out, but it should be done more gracefully (not with a Traceback).
