git解决The authenticity of host ‘github.com (192.30.255.112)‘ can‘t be established问题

报错完整信息

The authenticity of host 'github.com (20.205.243.166)' can't be established.
ECDSA key fingerprint is SHA256:p2QAMXNIC1TJYWeIOttrVc98/R1BUFWu3/LiyKgUfQM.
Are you sure you want to continue connecting (yes/no)?

1. 问题描述

新生成密钥的时候，git clone或者git push的时候，经常会报这样的错误：

The authenticity of host 'github.com (192.30.255.112)' can't be established.
RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8.
12

2. 问题原因

原因是少了一个known_hosts文件。本来密钥文件应该是三个，现在是两个，所以报了这样的错误。

3. 问题解决

此时选择yes回车之后即可，同时生成了缺少了的known_hosts文件：

Are you sure you want to continue connecting (yes/no)? //输入yes，回车
1

注意：
不是直接回车！是输入yes之后再回车！
