通过ssh连接github失败，将known_hosts中github相关的条目删掉！！！！

再次尝试

ssh -T [email protected]

Hi novaCoder-zrk! You've successfully authenticated, but GitHub does not provide shell access.

当通过ssh连接的github仓库尝试pull的时候，报错。

git pull kex_exchange_identification: Connection closed by remote host
Connection closed by 20.205.243.166 port 22 fatal: Could not read from
remote repository.

Please make sure you have the correct access rights and the repository
exists.

先把 .ssh 文件夹下的known_hosts known_hosts .old 中有关github的都删除。然后执行下面的语句：

ssh -T [email protected]

The authenticity of host ‘github.com
(20.205.243.166)’ can’t be established. ED25519 key fingerprint is

(yes/no/[fingerprint])? yes Warning: Permanently added ‘github.com’

当删除远程镜像，添加新的远程

 git branch --set-upstream-to=origin/master

把本地和远程镜像连接上。

然后 git pull
