It has now been over a year since Canonical took LXD away from the Linux Containers project and rebranded it as Canonical LXD. Those seeking support on LXD should reach out to Canonical directly.
Linux Containers is the home of the Incus project which is a proper open source alternative to LXD with full support from our community. You can learn about how to move from LXD to over to Incus here.
(Per our recent announcement, this topic will now be moved to the hidden LXD category and be closed)
