Not sure if this is possible, but here's my scenario -
1. Raspberry Pi Zero running Stretch Light
2. Setting up using headless WiFi method
--I add the ssh.txt and wpa_supplicant files to the boot directly, boots up great, auto connects to Wifi no problem, I can SSH right in. GREAT
3. Now I need to setup a USB Modem, that requires Network Manager
--I install Network Manager (apt-get install network-manager)...and here's where the problem occurs.
After Network Manager installs, it kills my SSH connection and I can't get back in (but remains connected to Wi-Fi). Unless I connect a monitor and keyboard to the Pi, however this is what I need to avoid.
Anyone know of a way to prevent Network Manger from overriding the SSH connection in this scenario?
