sometimes when installing a new operating system, the ssh key stored in
.ssh/known_hosts (on the machine your sitting at) is no longer the key
provided by the machine you're connecting to.   in the ssh client software
i use in a terminal window i get an error msg in that case, something to
the effect that there may be a man-in-the-middle or the remote machine
may have been compromised.   the solution in that case is to edit the file
known_hosts and delete the line for the remote machine that has been changed.

i can't say for sure that this is case when doing the upgrade you did, but
it definitely happens when you install a different operating system on a
machine and keep the same host name/ip address.
