This bug was fixed in the package netplan.io - 0.96-0ubuntu0.18.10.2
---------------
netplan.io (0.96-0ubuntu0.18.10.2) cosmic; urgency=medium
* d/p/0001-Partially-revert-the-change-for-enabling-systemd-net.patch:
Partially revert changes to networkd jobs ordering: leave systemd-networkd
enabled in multi-user.target instead of network-online.target, as in some
minimal setups there might be no job requiring network-online.target,
whereas the natural target to reach for booting is multi-user.target.

Bug description:
[Impact]
DHCP configurations where custom settings (routes, nameservers, etc.) need to
be applied.
[Test case]
1) Configure netplan for the particulars of the network by configuring an
appropriate dhcp{4,6}-override stanza:
network:
version: 2
ethernets:
engreen:
dhcp4: true
dhcp4-overrides:
use-dns: false
use-routes: false
route-metric: 3333
Additionally, if so required, add a custom DNS / routes to the
configuration. e.g.
nameservers:
search: [lab, kitchen]
addresses: [8.8.8.8]
(See https://netplan.io/reference#dhcp-overrides for the available
options)
2) Run 'netplan apply' or reboot to have the configuration applied.
3) Validate that the routes / DNS are properly ignored and/or replaced by the
defined values.
[Regression potential]
Minimal; this adds new values to the configuration generated for networkd or
NetworkManager. Existing configurations will remain unchanged, but new
configurations using the dhcp{4,6}-overrides fields will benefit from
additional flexibility.
---
Currently DHCP appears to be an all or nothing boolean, which is insufficient
for many network configurations.
Ideally all of the DHCP configuration options supported by systemd would also
be supported in netplan:
https://www.freedesktop.org/software/systemd/man/systemd.network.html#%5BDHCP%5D%20Section%20Options
As an example, consider the following netplan configuration:
network:
version: 2
renderer: networkd
ethernets:
enp0s3:
dhcp4: yes
nameservers: [8.8.8.8,8.8.4.4]
After running netplan apply I check the nameservers with systemd-
resolve --status and it shows:
DNS Servers: 8.8.8.8
8.8.4.4
192.168.1.1
Here, "192.168.1.1" was provided by my DHCP server. On this
particular node, I only want the manually configured DNS servers, but
netplan has no way to indicate this.
