请帮忙。我尝试osquery在我的 Ubuntu 上安装，结果如下：

Err:5 http://gb.archive.ubuntu.com/ubuntu jammy InRelease

我尝试移除按键，但还是出现此问题。我将不胜感激。

尝试

$> gpg --keyserver keyserver.ubuntu.com --recv-keys 871920D1991BC93C

进而

$> gpg --export --armor 871920D1991BC93C | sudo apt-key add - && sudo apt-get update

对每个丢失的钥匙重复上述步骤 - 你似乎有好几个。

编辑：

在 22.04 版之后，apt-key 显然已被弃用

来自手册页

   If your existing use of apt-key add looks like this:

   wget -qO- https://myrepo.example/myrepo.asc | sudo apt-key add -

   Then you can directly replace this with the following (though note the recommendation
   below):

   wget -qO- https://myrepo.example/myrepo.asc | sudo tee
   /etc/apt/trusted.gpg.d/myrepo.asc
