Changing /etc/network/interfaces does not set a static ip for BeagleBoard-xM running Ubuntu

[Max Mustermann]

Hi folks,

I'm going nuts. All over the internet it is said that setting a static IP is easy for BeagleBoard-xM running Ubuntu. Just change /etc/network/interfaces ...

One post suggests to just change the eth0-device. Another post changes eth0- and usb0-device as well. Both didn't work for me. As long as I don't thouch usb0 there is only one way to get the BeagleBoard connected - using the auto-config of eth0 via DHCP. And that's no good for I'd like to make the Beagle a Pi-hole ...

Can anybody please give me a hint how I can set the classic static 192.168.178.5 for my Beagle?

My first step after reading while waiting for approval (excuse my cross-posting) was

sudo systemctl disable connman.service

After reboot there was no connman anymore. But the appended /etc/network/interfaces still does not have any effect :-(

sudo cat /etc/network/interfaces

# This file describes the network interfaces available on your system

# The loopback network interface

Ubuntu 18.04 is wired to use netplan/sysetmd-networkd..

In my images, i replace that with connman..
