I think it may be related to
https://www.stgraber.org/2016/04/13/lxd-2-0-docker-in-lxd-712/
I have a docker container, with several dockers inside, and with lxd
snapshots.
Doing this:
# lxc delete docker
error: Get
http://unix.socket/1.0/operations/7d30bf41-3af6-4b48-b42c-06fdd2bba48b/wait:
EOF
Results in:
