/etc/ssh/ssh_config: terminating, 20 bad configuration options

Solution

Open the /etc/ssh/ssh_config and remove all the listed options. They are supposed to be part of the sshd_config (the server configuration), not the client one.

What did you do to /etc/ssh/ssh_config? Post the file contents in the question.

Have you check syntax with sshd -T command ?
