Add correct host key in /root/.ssh/known_hosts to get rid of this message

When try to login to remote server from my local machine using terminal I get the following message Please contact your system administrator. Add correct host key in /root/.ssh/known_hosts to get rid of this message. Offending ECDSA key in /root/.ssh/known_hosts:5 remove with: ssh-keygen -f “/root/.ssh/known_hosts” -R 45.55.154.139 Password authentication is disabled to avoid man-in-the-middle attacks. Keyboard-interactive authentication is disabled to avoid man-in-the-middle attacks.

I generated rsa key from server by using the following command

ssh-keyscan -t rsa ip_address

```added the rsa key to known_hosts file in my local machine, but still I am getting this issue

use this:

ssh-keygen -R SERVER_IP_ADDRESS

perhaps you need to use the correct host key type

grant@outhouse:~[20220830-13:40][#1003]$ ssh-keyscan -t ecdsa 10.1.132.201
# 10.1.132.201:22 SSH-2.0-OpenSSH_8.0
10.1.132.201 ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBD8srrJpp08VIkxLg08tK6gEGOWs5xCbeLppb/i8nYGcOXXpGa0UXMqfA8e8L20RtiY905osTH1mGFRSLRgV6ic=
grant@outhouse:~[20220830-13:41][#1004]$

then add this to ~/.ssh/known_hosts

ssh-keygen -f “/home/my_username/.ssh/known_hosts” -R “addr_of_remote_server”
