I'd like to address that 3rd question:  "Explain your approach, as an admin,  to resolve this ssh issue :"

To respond to this issue, I'm going to key (no pun intended) in on the very last message in the output: "permission denied (publickey)".  My research shows that this message is often produced when the permissions are “too open” on the SSH client.

If this is indeed the issue that is responsible for this message, just make sure that the permissions are correct on the the private key file on the SSH client.  This can be achieved with the following command:     #  chmod  600  ~/.ssh/private-key-filename

If I can locate a resource that provides an explanation/interpretation of each of the debug messages shown, I'll circle back to include that in my response.
