我正在使用 Ubuntu 16.04。我收到的错误如下：

有时应用程序甚至无法打开。

更新：sudo apt-get update现在运行没有错误，但我想知道这些更新是否足够？

您必须使用软件和更新（）禁用有问题的存储库software-properties-gtk。

你需要打开其他软件选项卡，然后禁用以下存储库：

  • http://archive.canonical.com/dists/precise（因为您的发行版是 16.04 LTS，即 Xenial Xerus）
  • https://packagecloud.io/computology/apt-backport/ubuntu（甚至浏览器也显示该页面为 404）
  • http://ppa.launchpad.net/picaso/octave/ubuntu（它不提供 Lucid Lynx 10.04 LTS 之后版本的软件包）

然后确认重新加载包缓存。

如果问题仍然存在 - 请sudo apt-get update手动运行并将错误输出添加到问题中。我随时准备为您提供更多帮助。
