Hi there,
Long time hassle-free AirVPN user with a first troubleshooting request after switching from Eddie-UI to the Bluetit stack (love your work!)
Looks as though the two processes are fighting for `/etc/resolv.conf` and causing issues with DNS. NetworkManager will rewrite the file on a Wi-Fi network change, causing loss of connectivity as local DNS is disallowed by the network lock. Can be worked around by stopping the Bluetit service, toggling Wi-Fi, then re-enabling; but this is tediou
Easiest way without breaking core network manager functionality is to work with its profiles. Create a dedicated profile with the DNS set to the servers in the specs. Switch manually between them before connection and after disconnection from AirVPN. NetworkManager will manage resolv.conf, and you can give Hummingbird/Goldcrest the -i switch.
If you're prepared to deal with divergent behavior, in /etc/NetworkManager/NetworkManager.conf, there in the [main] section, add the line:
dns=none
