sshd needs an additional reboot after the upgrade, either upgrading from
source or a binary upgrade. You may be unable to log in remotely otherwise.

On the client side you will see

kex_exchange_identification: read: Connection reset by peerConnection
reset by x.x.x.x port 22lost connection

/var/log/messages will be filled w fatal: recv_rexec_state: parse config
errors.

service sshd restart resolves it if you can get console access.
