It's failed after I run lxd init --auto:
$ lxd init --auto

I've been trying reinstall a lxd but error appears again (lxd installed using snap).
I know that this question is old, but I had same problem. After googling error message ended up here. Still there is no solution so this might help: In my case lxc wrongly detects that I'm using nftables instead of iptables because iptables was empty. I've added one iptable rule, restarted lxd and it's now working. More information: https://github.com/lxc/lxd/issues/8724
