Cannot push files because key fingerprint doesn't match my saved SSH key #48086

Problem with SSH key I created a new SSH key and saved it to my account, deleting my old one. Now when I try to push my files to a repo, I'm getting this error: The authenticity of host 'github.com (140.82.112.4)' can't be established. Please make sure you have the correct access rights The key fingerprint shown above does not match the SSH key I saved. How do I fix this? |

Thanks so much! I'm a student doing Springboard's software engineering bootcamp and use Github frequently to upload exercises and projects but I'm still a newbie and have lots to learn! I appreciate the support! |

That message is not about your key, it's about the key used to identify the GitHub server. SSH uses authentication with the host key to ensure no-one can trick you into connecting to an attacker's server instead. But SSH can't know if the host key is the right one for that server by itself, so it's asking you to check if that key is correct for GitHub publishes their key fingerprints here: https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/githubs-ssh-key-fingerprints Make sure the fingerprint you're seeing is one of those (depending on the key type), and accept if it is. SSH will remember that for future connection. If the key fingerprint you see is not on the list, figure out who's messing with your network. |
