First, let's see if you have the right interface. ip link show |grep enp0s1 if that doesn't show you a line of config, you are specifying the wrong interface. ip link show will show all of them to you. Second, let's see if something else is doing the configuration: grep -C1 ifupdown /etc/NetworkManager (you want this to show managed=false) ls /etc/systemd/network/ (you would like this to be empty) Let us know what you find out. -dsr-
