Hi Christof, this worked for me:
cat /etc/default/lxc-net USE_LXC_BRIDGE="true" cat /etc/lxc/default.conf lxc.net.0.type = veth lxc.net.0.link = lxcbr0 lxc.net.0.flags = up lxc.apparmor.profile = generated lxc.apparmor.allow_nesting = 1 and don't forget to start the lxc-net service before starting any container: sudo systemctl start lxc-net Paolo
