Troubleshooting new LXD deployment

Hi all,

I have downloaded an LXD image (ubuntu focal) from the market place to try it out but it failed upon launch. One of the error in the log is
Thu Sep 3 21:32:27 2020 [Z0][VMM][I]: Command execution fail: cat << EOT | /var/tmp/one/vmm/lxd/deploy ‘/var/lib/one/datastores/107/58/deployment.0’ ‘lxd01’ 58 lxd01

What steps should I take to troubleshoot this problem? Thanks.
