[erlang-bugs] Error on running Erlang SSH server

[Daniel Goertzen]

I followed the code here (
https://github.com/erlang/otp/blob/OTP-17.0.2/lib/ssh/src/ssh_transport.erl#L374
)

It tells me that the client and server share no host key algorithm.  Did
you setup a host key(s) for the server?

I think the code should crash at line 374 instead of returning undefined
and crashing in a more obscure place, but perhaps there are other reasons
for that.
