Kali Linux不更新

Question

我正在尝试更新我的kali版本，但是每当我尝试执行sudo apt update命令时，它都会给出以下输出：

我尝试过更新我的/etc/apt/resources.list文件，但是仍然存在相同的问题，我甚至不知道输出中这些ubuntu消息是什么。现在，resources.list文件如下：

deb http://http.kali.org/kali kali-rolling main contrib non-free

Answer 1

resources.list不是一个适当检查的文件，除非卡利做了一些非常不明智的事情。

正确的文件是/etc/apt/sources.list/，更近期的版本也将查找与/etc/apt/sources.list.d/*.list匹配的文件。

您正在展示的输出表明，apt试图从多个Ubuntu存储库中读取数据，并抛出一系列错误，因为它在其信任列表中没有相应的GPG键--这是不应该的，因为Kali不是Ubuntu，并且试图将其中一个安装到另一个库中会导致各种混乱。

将存储库设置修复为只使用kali链接，然后再试一次。

另外，请记住，卡利而非用于一般桌面使用和重新安装有一个正确的桌面导向系统。
