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互联网的本地网络上使用。我遵循了几个网站上的说明，主要是这个一，显示了如何使用 apt-mirror 执行此操作。我相信我已经正确设置了服务器。它下载了 Gb 的数据并说它成功了。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 bionic 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。现在它看起来像这样：

我在下载之前还修改了 mirror.list 文件以提取 bionic，在我的 dists 文件夹中 bionic 就在那里，并且充满了软件包。然后我运行 sudo apt-get update 并得到了以下输出：

我尝试安装了一些基本软件包，但到目前为止，我总是收到相同的消息，说找不到它。有人知道这里可能出了什么问题吗，或者我可以尝试找出如何解决这个问题？
答案1
问题一：
如果你查看修改后的 mirror.list 的底部，会发现这行有问题：
E: Repository 'http://dl.google.com/linux/chrome/deb stable Release' changed its 'Origin' value from 'Google, Inc.' to 'Google LLC'
我刚刚遇到了同样的问题，这很容易解决。发生这种情况是因为拥有 APT 存储库的公司已将其名称从 Google Inc 更改为 Google LLC。打开终端并输入：
sudo apt update
然后，系统将提示您接受存储库的新来源：
Do you want to accept these changes and continue updating from this repository? [y/N]
输入“y”就可以了。就是这样。
问题二：
看看是否存在：
/etc/apt/apt.conf.d/50appstream
如果存在，则需要像这样删除：
sudo rm /etc/apt/apt.conf.d/50appstream
下一个
可能需要将架构添加到 sources.list 中，类似以下示例：
deb [arch=amd64] file:/wherever ubuntu bionic main restricted universe multiverse ...etc.
更新现在应该可以生效了。
