Well, at least in my case, I found that all the sshd host keys were

I don't know if it's related but this is the log of trying to use that
RSA key to connect to a server:
debug1: Trying private key: /etc/ssh/ssh_host_rsa_key
debug1: key_parse_private2: missing begin marker
debug1: key_parse_private_pem: PEM_read_PrivateKey failed

Looks to be a "No supported key exchange algorithms [preauth]" problem.
Regenerating the host RSA key with "ssh-keygen -t rsa -f
/etc/ssh/ssh_host_rsa_key" fixes the issue
Log of failure (pre-keygen) on host:

My cases of this bug (though it seems like there are different ones with
similar symptoms) happen each time I reset a 14.04 VM to an older state
from a hard shutdown. Localhost ssh connections fail as well with same
output.
Workaround for me is regenerating the host keys (sudo rm /etc/ssh/host_*
