ssh pi@192.168.7.76 @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that a host key has just been changed. The fingerprint for the ECDSA key sent by the remote host is SHA256:6LCvezi2d/0iI+rsotNU76MUpwva2RBBASrp1K+W9Fc. Please contact your system administrator. Add correct host key in /Users/wtsang/.ssh/known_hosts to get rid of this message. Offending ECDSA key in /Users/wtsang/.ssh/known_hosts:4 ECDSA host key for 192.168.7.76 has changed and you have requested strict checking. Host key verification failed.

Solution: reason of failure due to usage of same IP which was used previously for a different pi. Assign another IP to the new pi. Deleting the unused $HOME/.ssh/known_hosts entry of the unused host may work also.
