I've just installed Ubuntu 18.04 x86-64 with the Mate environment. When I found that the fancy new way to configure your network is netplan, I gave it a try and created a config like below:
network: version: 2 renderer: networkd wifis: wlp1s0: dhcp4: yes dhcp6: yes access-points: "mywifi": password: "mypassword"
This works well and I kind of like it, after getting used to it. But when I start the Mate desktop, I now have two network icons next to the clock. I found that network-manager is still installed. As I use "networkd" in my config: can I safely purge network-manager and its plugins or will I run into problems?
