为什么会发生这种情况？我该如何修复它？

答案1

每：https://twitter.com/kalilinux/status/959515084157538304，您的存档密钥环包已过时。您需要执行此操作（以 root 身份）：

wget -q -O - https://archive.kali.org/archive-key.asc  | apt-key add

答案2

尝试这个：

wget https://http.kali.org/kali/pool/main/k/kali-archive-keyring/kali-archive-keyring_2018.1_all.deb
apt install ./kali-archive-keyring_2018.1_all.deb
apt-get update

卡利论坛如果这不起作用，您可以在该线程中进一步查找。

答案3

您缺少 Kali 用于签署其包的密钥。您可以使用gpg下载密钥并apt-key add添加它：

gpg --keyserver pgpkeys.mit.edu --recv-key  ED444FF07D8D0BF6
gpg -a --export ED444FF07D8D0BF6 | sudo apt-key add -
