Identification error from host in SSH host key change


It happens because the public key of the remote machine has changed since your last login or if you reinstall the OS on your server.
1. Try to delete the known_hosts file:
rm ~/.ssh/known_hosts
2. Or to disable SSH key checking :
Go to the ~/.ssh/config (if doesn't exist, create it)
Host *
StrictHostKeyChecking no
This will turn it off for all hosts you connect to.
You can write hostname pattern instead of * if you want to apply to only some hosts.
