I would like to switch to the native udev:armhf package on the Ubuntu image. (This is a requirement for Openhab to run properly) But the service is not starting up after the switch. This is the output from the installation:
rock@openhabianpi:~$ sudo apt-get install udev:armhf
[sudo] password for rock:

And this is the output from systemctl status systemd-udevd.service:

But if I run sudo /lib/systemd/systemd-udevd I get no errors. Any ideas what could cause this problem? By the way, on the debian image the udev:armhf package seems to be installed by default.
