Public bug reported:

When connecting to a host whose host keys have changed (e.g. when
connecting to a new instance in a cloud), something like the below
message is displayed. The ssh-keygen invocation is harder to copy-paste
than it could be if it were on a separate line.

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    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
<REDACTED>.
Please contact your system administrator.
Add correct host key in /home/<user>/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /home/<user>/.ssh/known_hosts:408
  remove with: ssh-keygen -f "/home/<user>/.ssh/known_hosts" -R <REDACTED>
ECDSA host key for <REDACTED> has changed and you have requested strict checking.
Host key verification failed.
