On a fresh installation of Ubuntu desktop (ubuntu-18.04.2-desktop-amd64) connecting an Android phone and enabling USB tethering automatically brings up a DHCP configured network adaptor:

Attempting the same process on exactly the same hardware but using Ubuntu Server (ubuntu-18.04.2-live-server-amd64) (output is hidden from ifconfig as the adaptor is down):
ifconfig -a

TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
i.e. the adaptor has been detected here but does not appear to have been automatically configured.
While its possible to manually bring this adaptor up by modifying /etc/netplan/50-cloud-init.yaml:
network:
ethernets:
ens192:
dhcp4: true
ens194u1u2:
dhcp4: true
version: 2
and then running:
sudo netplan apply
I'd ideally like the behaviour to match the desktop version, i.e. when tethering the phone the adaptor is automatically configured for DHCP and brought UP.
Can anyone clarify what packages or config I need to change in the server version to achieve that?
