Here is my defualt.conf: cat ~/.config/lxc/default.conf

lxc.net.0.type = veth
lxc.net.0.link = lxcbr0
lxc.net.0.flags = up
lxc.net.0.hwaddr = 00:16:3e:xx:xx:xx
lxc.idmap = u 0 231072 65536
lxc.idmap = g 0 231072 65536

getting the following error after running: lxc-create --template download --name unpriv-cont-user
