Yes, this is actually the expected behavior. If netplan is configured to
use the systemd-networkd backend for a given network interface (i.e. as
set up by a default server installation) the "graphical UI"
(NetworkManager) will ignore that interface; otherwise there would be
conflicts
As you mentioned this can be changed by adopting the netplan
configuration in /etc/netplan/*.yaml, defining the NetworkManager
renderer, after which the interface will be handled by NM and can be
controlled through the "graphical UI" and other NetworkManager tools,
like "nmcli".
I don't think the user's configuration should be overwritten by
installing a meta-package like "ubuntu-desktop".

Title:
installing ubuntu-desktop package on ubuntu-server breaks wlan-config
in netplan
Status in network-manager package in Ubuntu:
Won't Fix
Status in network-manager-applet package in Ubuntu:
Invalid
Status in nplan package in Ubuntu:
Won't Fix
Bug description:
Installing Ubuntu 17.10 server uses netplan for wlan-configuration, if
the wlan-device is the primary device.
After this, installing the ubuntu-desktop package leaves the netplan-
config untouched, so that the graphical wlan search is unsuccessfull.
After deleting the netplan-file in /etc/netplan/ or setting it to
network:
version: 2
renderer: NetworkManager
the graphical wlan search works without further problems.
Im not sure, where is the best place to repair this issue.
- using network-manager also in server environment
- replacing netplan-file while installing ubuntu-desktop
- adding some extra config in netplan-directory, so the network-manager
support is additive (is this possible?)
- remove the netplan-config while installing ubuntu-desktop
