这个问题遇到好多次了，一直懒得解决，但是每次向 github 提交/拉取代码，真的很烦躁，不得不解决一下了。
警告信息
> git pull
Warning: the ECDSA host key for 'github.com' differs from the key for the IP address 'x.x.x.x'
Offending key for IP in ~/.ssh/known_hosts:17
Matching host key in ~/.ssh/known_hosts:26
Are you sure you want to continue connecting (yes/no)?
解决方法
x 部分，替换成对应 IP
> ssh-keygen -R x.x.x.x
# Host x.x.x.x found: line 17
~/.ssh/known_hosts updated.
Original contents retained as ~/.ssh/known_hosts.old
ssh-keygen -R 参数说明
man ssh-keygen
-R hostname | [hostname]:port
Removes all keys belonging to the specified hostname (with optional port number) from a known_hosts file. This option is useful to delete hashed hosts (see the -H option above).
造成这个问题的原因
This error usually occurs when the host key for GitHub has changed, which can happen for a variety of reasons such as server maintenance or security updates. To fix this, you need to update your known_hosts file with the new host key for GitHub.
