我最近将系统升级到 Debian 12，当我尝试运行时我注意到这些错误
sudo apt update
这是我的输出：

另外，我当前的sources.list 文件：

起初，我还遇到了一些针对 Nodejs 和 vscode 存储库缺少签名的错误。因此，我重新安装了这些应用程序，它们似乎添加了一个.gpg文件，/etc/apt/keyrings并且我注意到 /etc/apt/sources.list.d/ 下的相应条目已更新为signed-by=/etc/apt/keyrings/....之后这两个额外的NO_PUBKEY错误就消失了，这绝对是有道理的。
我对为什么这更安全有一些了解，但我缺少的是当涉及到 debian 存储库时我从哪里获得这些密钥。
我是否遗漏了什么，或者从 11 升级到 Debian 12 时我是否可能弄乱了一些东西？
谢谢！
