我正在为非洲的人道主义任务做准备，我们会把两台笔记本电脑留在互联网连接成本低的地方。我宁愿运行 Ubuntu，而不是“另一个更不靠谱的选择”。
因此，为了更新以及设置适应性（即使用应用程序库），我想创建一个Xenial 仓库的本地镜像放在 USB SSD 硬盘上，以便他们可以物理地连接到更连通/更便宜的插座。我一直在使用apt-镜像根据这个指示教程到目前为止（注意，法语在前，但我想这已经足够标准了）。
我正在运行以下所有内容Ubuntu 16.10系统。
我的消息来源如下：
deb [arch=amd64] file:/media/andre/Depots/miroir/mirror/archive.ubuntu.com/ubuntu/ xenial multiverse universe main
deb [arch=amd64] file:/media/andre/Depots/miroir/mirror/archive.ubuntu.com/ubuntu/ xenial-updates multiverse universe main

deb [arch=amd64] file:/media/andre/Depots/miroir/mirror/archive.ubuntu.com/ubuntu/ xenial partner
我在执行“时遇到错误sudo apt-get 更新“基于未发现的组件-amd64.yml文件，而有一个组件-amd64.yml.gz目标存储库中属于 root 的具有混乱权限（-rw-----）的文件。

我发现了一些与权利和特权有关的报告。我还遇到了另一份与dep11文件并决定根据评论采取行动

因为有一个获取失败对于一些dep11文件
我的conf apt-miror文件因此变成：

我决定重置整个混乱并重新下载仓库。
启动时apt-get 更新，有一个毫无根据的“包裹“文件以及一些”组件-amd64.yml" 文件。

似乎有一些符号链接，除了我添加的 2 个“.yml”文件外，其他文件都指向档案。而那 2 个文件带来了错误报告。
我真的力不从心，而且我已经尝试了一段时间才成功。有什么想法吗？
答案1
在客户端，这似乎是一个漏洞。我在全新安装 17.04 时也遇到了类似的问题。
发出命令appstreamcli refresh --force为我解决了这个问题。
