IDK this has anything to do with the problem you're seeing (unless you
have something wacky with your ~/.ssh - like it symlinked to /etc/ssh
or something). So, I'll just go on the assumption that this is
coincidence...

The host keys are in known_hosts, but are the proper keys (the one you
listed above - see ssh-keygen -lf /etc/ssh/ssh/ssh_host_rsa_key.puh on
the server) listed there? Does your user own the file and is it mod
660 or less? Are you logging into the server you think you are (did
you typo an ip in your ssh_config or is someone mitm you)?
