由于 Internet 故障，我无法使用 GUI 更新程序更新我的计算机

我打开 GUI 更新管理器进行更新。但它给了这个窗口：

所以我再次点击尝试，它做了同样的事情。然后我点击设置...看看我是否破坏了某些东西。

我看不出问题。我确实注意到一些源代码正在下载。我不想要它。所以我取消了源代码，然后单击关闭。它给出了这个窗口：

    看起来您的 /etc/apt/sources.list 文件可能有重复的条目，我可以在 pastebin 中看到。我会使用 nano 或 gedit 等文本编辑器手动删除这些行。

    并且未能下载存储库信息是由于在 sources.list 文件中有一个不存在的存储库 - 看起来 Xenial 的额外存储库尚不存在。删除该行 deb http://extras.ubuntu.com/ubuntu xenial main 应该可以修复更新。

    之后我也会做'apt-get clean'。
