就在不久前，我在推送到 GitHub 时开始收到此警告。

WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!

IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.

这是正常现象吗？我该如何解决？

我无法ssh和rysnc到远程系统.它不断给出此错误消息:

WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     

IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!

打开 bitbucket 时，我在 Snackbar 上收到一条消息，上面写着“SSH 主机密钥轮换”，它的真正含义是什么？我需要做点什么吗？

SSH 主机密钥轮换

重要通知：Bitbucket Cloud\xe2\x80\x99s RSA SSH 主机密钥将于 2023 年 6 月 20 日 1700 UTC 轮换

我的计算机上安装了多个虚拟机，通过 ssh 连接到它们：

ssh vm1@localhost\n

或者

ssh vm2@localhost\n

因此，每次连接到不同的虚拟机时，我都需要编辑~/.ssh/known_hosts文件以删除： \xe2\x80\x9c WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!\xe2\x80\x9d 消息。

有没有办法自动信任本地主机上的所有虚拟机？

我正在尝试使用 Remote-SSH 扩展来编辑 Debian 服务器上的文件。SSH 连接已正确建立，但随后我收到一条错误消息：

Failed to connect to the remote extension host server

和日志：
