Help with Network Manager

Configuration
#1

I have Home Assistant Supervised. In order for it to be a supported install, I am required to run Network Manager. I have it installed and set up like here: Network Manager - Home Assistant

The one difference is that I have assigned a static IP address. So my /etc/network/interfaces file look like this:

source /etc/network/interfaces.d/*

auto lo
iface lo inet loopback

iface enp0s3 inet static
address 192.168.xxx.x
netmask 255.255.255.0
gateway 192.168.xxx.x
dns-nameservers xxx.xx.x.xx, xxx.xx.x.xx

The problem is every time I reboot the network manger is clearing the /etc/resolv.conf file and leaving it empty. Then if i try to execute a sudo apt-get update, it cannot find any of the locations.

#2

Run sudo nmtui and use it to configure static IP, etc.

OK, do I then make the /etc/network/interfaces file like what was shown in the Network Manager link and make iface enp0s3 auto?

#4

Just use nmtui (it configures NetworkManager) then reboot.

One other quick question. Is there a link to a web page somewhere that tells me to do that? I was not familiar with that UI.
