He or she won't get a warning. The connection will simply break like the
one the OP posted. He might check if he changed the keys in /etc/ssh
during the upgrade. If so, the entries for the server in the
ssh_known_hosts files on the clients have to be deleted prior to a new
login. Because of the security problem with OpenSSL on Debian [1] it
might be risky to restore the old keys from backup.

Yes, you get a warning about a possible man-in-the-middle attack
because the key changed.
