Now I'm having issues with starting the LND, if I manage to start it (asking for wallet password), I'll post it here.
2018-03-30 22:16:18.654 [INF] LTND: Waiting for wallet encryption password. Use `lncli create` to create wallet, or `lncli unlock` to unlock already created wallet.
did you run lncli create/unlock without errors?
No, it gave me some error, but I've managed to skip this with using the --noencryptwallet flag when starting lnd. It opens the wallet and lnd continues to start. (This leaves the wallet.dat unencrypted, but for testing purposes for the first start it's fine for me.)
Now I'm waiting for lnd to find some proper nodes, but it's struggling to find any. Maybe it's because of the beta upgrade, nodes needs to upgrade before they will be able to serve neutrino type nodes, so I'm trying to start it periodically, and also checking github, e.g.:
