Lxd 3.0.1 with kernel 4.18

Hi!!

I was reading article Behind the scenes with Linux containers https://opensource.com/article/18/11/behind-scenes-linux-containers and while trying the example with lxc-execute I ended up with the errors below. Is there any way to fix this behavior?

$ sudo lxc-execute --name basic --rcfile ~/lxc/mycontainer.conf /bin/bash --logfile ~/lxc/mycontainer.log
lxc-execute: basic: utils.c: safe_mount: 1130 No such file or directory - Failed to mount /dev/pts/2 onto /dev/console
