但是，当我运行 时apt update，我无法从 Archive 存储库中检索软件包（但是 stable/oldstable/oldoldstable 存储库工作正常），因为公钥存在问题：

所有谈论此事的资源都建议安装debian-keyring和debian-archive-keyring包，但我已经拥有它们了，而且这似乎没有任何作用。
有人有解决方案吗？
答案1
来自文章 修复 Debian 中的 Apt-get：NO_PUBKEY / GPG 错误：
基于使用Linux内核的Debian操作系统的计算机中，可能会出现类似NO_PUBKEY的错误信息。这种情况发生在使用Apt-Get命令行工具时，此错误与该工具的更新功能有关。
只需输入适当的命令即可解决此问题。
针对此修复的建议命令是（针对密钥服务器pgpkeys.mit.edu）：
gpg --keyserver pgpkeys.mit.edu --recv-key [key-name]
gpg -a --export [key-name] | sudo apt-key add -
您的错误消息中提到的键是：AED4B06F473041FA、64481591B98321F9、4D270D06F42584E6 以及其他（似乎很多）。
对一个键尝试此建议，并检查是否至少有一个错误消息已解决。如果已解决，请对其他键重复此操作。
