我正在尝试在本地服务器上设置 Ubuntu 软件包的镜像，以便在长时间不连接到 Internet 的本地网络上使用。我遵循了一些站点的说明，主要是这个站点，它显示了如何使用 apt-mirror 来执行此操作。我相信我的服务器设置正确。它下载了 Gb 的数据并表示成功。然后我设置了一个 nginx 服务器，我可以使用我的 ip 地址访问该站点并查看文件夹以及 dists 和 pool 文件夹。dists 包含其中的仿生文件夹。然后，我修改了客户端计算机上的 /etc/apt/sources.list 文件，并将其更改为指向我的服务器的 IP 地址，而不是 ubuntu 存档站点。这是它现在的样子：

我已经尝试安装一些基本软件包，但到目前为止，我总是收到相同的消息，说找不到它。有没有人对这里可能出现的问题有任何想法，或者我可以尝试找出如何解决这个问题？
