@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@  
@ 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  
SHA256:77ydSU9ntFztbasTwkMk5z6Ke6cippOq2VVjnSbGs48.  
Please contact your system administrator.  
Add correct host key in C:\Users\Andreas/.ssh/known\_hosts to get rid of this message.  
Offending ECDSA key in C:\Users\Andreas/.ssh/known\_hosts:3  
ECDSA host key for 192.168.0.21 has changed and you have requested strict checking.  
Host key verification failed.

This is just a warning from the `ssh` client - every time you write a new OS image for Raspberry Pi, it usually causes the systems unique finger print to change, see: [https://stackoverflow.com/questions/20840012/ssh-remote-host-identification-has-changed](https://stackoverflow.com/questions/20840012/ssh-remote-host-identification-has-changed)

The simplest solution is to delete this file: `C:\Users\Andreas/.ssh/known_hosts` and try again.
