I am experiencing the similar network issues. My C2 didn't get an IPv4 address via DHCP only an IPv6 address. I have to use my router to figure out that IPv6 and connect to it. With the hints from Igor I got IPv4 also working: systemctl disable NetworkManager Add add the following to `/etc/network/interfaces`: auto eth0 iface eth0 inet dhcp iface eth0 inet6 auto privext 0 `privext 0` is optional. It disables the IPv6 privacy extension for server use. I had a lot of trouble with that too before I disabled NetworkManager. And of course: reboot I hope this will be fixed soon.
