无法从Ubuntu Xenial本地存储库安装软件包
我使用apt-mirror为Xenial创建了一个本地仓库。
当我在另一台机器上尝试sudo apt-get update时（当然，我配置了web服务器），我收到以下错误，我无法从本地仓库安装任何软件包。 可以做些什么？

听起来您的本地软件包存储库不同步，或者您要安装的软件包列表不同步。
404 Not Found表示软件包在系统所需的存储库中不可用，因此您在此处只有几个选项。
如果存储库不同步：
使用主存储库重新同步存储库，在同步完成后，在使用它的系统上正常运行apt-get update 。
如果重新同步存储库不起作用：
告诉计算机使用archive.ubuntu.com （或其中一个国家/地区镜像）服务器来获取更新。
