无法“git pull” - 主机密钥验证失败

Not able to "git pull" - Host key verification failed

提问by Richard

I've got root access to our production server and I want to deploy the latest version in git to the server but I'm running into the error below when I "git pull" on the folder I want to update.

我对我们的生产服务器有 root 访问权限，我想将 git 中的最新版本部署到服务器，但是当我在要更新的文件夹上“git pull”时遇到以下错误。

I've browsed around a bit, but can't find a clear answer on what to do..

我已经浏览了一些，但找不到关于该怎么做的明确答案..

The staging server runs on the same machine, but just in a different folder and when I pullon that folder it all goes fine.

临时服务器在同一台机器上运行，但只是在不同的文件夹中，当我pull在该文件夹中时，一切正常。

I'm not very experienced when it comes to Linux, so please help me out with a clear answer on how to fix :-)

我对 Linux 的经验不是很丰富，所以请帮助我明确回答如何修复:-)

Otherwise I have access to anything I need

否则我可以访问我需要的任何东西

p.s. This has worked in the past, so I'm assuming it's got something to do with the SSH key

ps 这在过去有效，所以我假设它与 SSH 密钥有关

In the log you see the following text:

在日志中，您会看到以下文本：

(...)

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:1
remove with: ssh-keygen -f "/root/.ssh/known_hosts" -R gitlab.site.org

Host key verification failed.

So it is a matter of performing the command that is suggested there:

所以这是执行那里建议的命令的问题：

ssh-keygen -f "/root/.ssh/known_hosts" -R gitlab.site.org

按照这些对我有用的步骤后，我也遇到了同样的问题。

For macOS:

对于 macOS：

Step 1: Go to Folder or use command+shift+g
