Not quite an answer that you asked for, but you could use Ctrl+U to clear everything you have typed up to that point and try again without ‘forcing a wrong unlock’

Go applications are statically built. So you don’t really need anything special on the server for that. Anything will do. Debian would be fine here.

Best fit is always dependent on how you’re planning to use it. Find out what your requirements before you set up a server.

Generally Debian is chosen very often, but I’d wager pretty much any distro will do. Your own experience goes a long way in making a distro a good choice.
