I have installed Ubuntu 18.04 on a Surface Book with dual boot, and I can't get the ethernet connection to work. Although the wifi connects, I keep getting the "activation of network connection failed" error for the ethernet.
sudo lshw -C network gives me:

But I suppose this is not near enough information to investigate. Please let me know what else is useful to know in this case, and I'll add that to the question.
PS: I saw this question, but I have all the updates installed, and I still can't connect, so this is not a duplicate.
UPDATE: Before turning off the computer, I turned off the cable connection in Settings. Today when I turned it on, the ethernet button is gone:
