2020-11-11 13:02:58.285 [INF] LTND: Waiting for wallet encryption password. Use `lncli create` to create a wallet, `lncli unlock` to unlock an existing wallet, or `lncli changepassword` to change the password of an existing wallet and unlock it.

Expected behavior
xud unlock prompt to come up and let me enter xud ctl.

I'm getting this same issue on master when trying to start up an xud-docker environment from scratch using master - it's preventing me from using xud-docker. Any suggestions on a workaround until this is fixed?

[kilrau]

docker exec -it mainnet_xud_1 xucli unlock

[sangaman]

docker exec -it mainnet_xud_1 xucli unlock

Works as advertised.
