Comment 10 for bug 1733322

I have tried the workaounds listed here
https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1733322

> 1. Change "managed=false" to "managed=true" in /etc/NetworkManager/NetworkManager.conf as suggested in https://askubuntu.com/a/2905
> 2. Touch /etc/NetworkManager/conf.d/10-globally-managed-devices.conf as suggested in https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1676547
> 3. Change renderer to NetworkManager in /etc/netplan/01-netcfg.yaml

(I didn't need to do 3 as it was already set like that)

But its still broken.
