Error in network definition: unknown key dhcp4-overrides
I am trying to set up Ubuntu 18.04 LTS, which appears to be using netplan to configure networking. In this case I need to override the DNS servers provided by DHCP and use manually assigned nameservers. So I modified the netplan configuration as follows:
# For more information, see netplan(5).
network:
version: 2
renderer: networkd
ethernets:
enp2s1:
dhcp4: yes
dhcp4-overrides:
use-dns: false
dhcp6: yes
dhcp6-overrides:
use-dns: false
nameservers:
addresses: ["fd35:2ff0:b0b9:d0c0::1:1", 192.168.255.17]
In another question, and on netplan.io, it was explained that netplan had options dhcp4-overrides and dhcp6-overrides which would permit this, but these don't appear to work. netplan generate or netplan apply gives the error:
Error in network definition //etc/netplan/01-netcfg.yaml line 6 column 6: unknown key dhcp4-overrides
How, then, can I be sure that my specified nameservers will be used, and the nameservers obtained from DHCP will never be used? I'm willing to toss netplan in the bin if necessary.

I'm about halfway to throwing netplan in the bin, but I have a workaround that appears to work.
Seeing that it was rendering to networkd, and that systemd-resolved was handling DNS, I just created the relevant configuration directly.
I dropped the dhcp overrides bits from netplan, leaving me with only:
# For more information, see netplan(5).
network:
version: 2
renderer: networkd
ethernets:
enp2s1:
dhcp4: yes
dhcp6: yes
Then I created a file /etc/systemd/resolved.conf.d/dns.conf to specify the DNS servers I needed:
[Resolve]
DNS=fd35:2ff0:b0b9:d0c0::1:1 192.168.255.17
