Because of the new beta version of LND, I've deleted the previously installed LND and BTCD from the PI and started from scratch. I would like to start a neutrino version of the LND, so according to my current understanding, BTCD is not necessary at all, but I'm not 100% sure yet. This can change in the future as I move forward with testing this thing.
Hint: if you want to start to risk your coins on the main net, you should modify the config.go file in the src directory:
if cfg.Bitcoin.Node == "neutrino" && cfg.Bitcoin.MainNet {
str := "%s: neutrino isn't yet supported for " +
"bitcoin's mainnet"
err := fmt.Errorf(str, funcName)
return nil, err
}
If you comment these lines out (you put // at the beginning of the line) you won't have an error message (and won't stop you) when you want to start your lnd client in neutrino mode on the mainnet.
After saving the config.go file, I have installed the new LND again (the process is the same as above, it just installs the new version).
Now I'm having issues with starting the LND, if I manage to start it (asking for wallet password), I'll post it here.
