I use lxd all the time on my classic Ubuntu 16.04 and 18.04 systems, but I’m having trouble running it on a pure core system. Is it supposed to work on core?
popey@localhost:~$ lxc list
Error: Get http://unix.socket/1.0: dial unix /var/snap/lxd/common/lxd/unix.socket: connect: permission denied
Using extrausers. Conveniently, here’s a comment with the right steps, and further down, a comment about the lxd snap needing root unless that group exists.
