You can remove net.enp38s0 service from the default runlevel and reboot, with an eye on the log messages. > Aug 22 09:24:29 ACM /etc/init.d/net.enp38s0[2695]: The dhcpcd version > is too old. Please upgrade. I'm running the same version like you and do not see this message, but this does not explain why you get this printed out. I expect you have the dhcpcd service enabled. Does your NIC come up and obtain an IP address via dhcpcd, if you remove dhcpcd from the default runlevel? Careful you do not lock yourself out, if this is a remote system and no network comes up when you reboot. > Aug 22 09:24:29 ACM > /etc/init.d/net.enp38s0[2527]: ERROR: net.enp38s0 failed to start > > .. > > So it would appear that everything is working, but I still get error > messages.
