The interface enp8s0 is the physical Ethernet port from the Ubuntu host that is directly connected to the BB, correct? If this is correct, then enabling DHCP makes no sense unless you have set up the BB as a DHCP server. Since you are connecting these two devices directly, then you need to either hardcode the IP address on the host without DHCP and then set the IP on the BB. If you do what I had shown previously, then that will give a clue if the connection is working.
However, using Network Manager may interfere with any manual changes you make. Please look at the link I provided for more detail on how to troubleshoot a network connection.
