错误背景：

1、Ubuntu上面作为运行环境，Coding在本机的windows环境

2、在windows上安装sublime 3，然后保存代码通过xftp保存到Ubuntu虚机上面。

3、Ubuntu重装系统

4、然后使用sublime 下载新目录的代码，然后就报错了

错误内容：

Connecting to SFTP server "192.168.14.105" as "root" ......... failure (Host key verification failed)
The SSH host key has changed. This could indicate a potential security breach, or that the domain you are connecting to recently moved servers.
If you are confident this is not a security breach you can delete the old host key and try again.
1. Win XP: Start > Run > regedit.exe
Win Vista/7: Start > regedit
2. Expand to HKEY_CURRENT_USER\Software\SimonTatham\PuTTY\SshHostKeys and delete the entry including @22:192.168.14.105

原因：因为sublime 在windows的注册表中把192.168.14.105的值注册，不能重新注册。

错误解决办法：

1、ctrl + R ，输入 regedit

2、删除HKEY_CURRENT_USER\Software\SimonTatham\PuTTY\SshHostKeys下的 rsa2@22:192.168.14.105
