What do you get if you do "journalctl -u snap.lxd.daemon -n 300" and anything useful looking in /var/snap/lxd/common/lxd/logs/lxd.log? It's expected that "systemctl start lxd" won't work anymore since the data was moved over to the snap which then likely caused your database to be upgraded, making it unreadable for your older deb version of LXD. I'd recommend you do: - systemctl stop lxd lxd.socket - systemctl mask lxd lxd.socket To prevent any accidental startup of your old LXD until the snap migration is done and it can be safely removed. -- Stéphane Graber Ubuntu developer http://www.ubuntu.com
