Question

我最近从 Ubuntu 转到 Lubuntu 19.10，并且删除了通常使用 GNOME 的软件包。不幸的是，我删除了我的软件中心和更新中心。我现在无法更新我的系统，这真是一团糟。当我尝试运行sudo apt update

你显然是从其他地方复制了这些更老的资料，这是不明智的。

这不起作用，因为 Eoan (19.10) 还不是旧版本（不受支持）：

deb http://old-releases.ubuntu.com/ubuntu eoan main restricted

相反，尝试这样做：

deb http://releases.ubuntu.com/ubuntu eoan main restricted

当您检查并更正所有行上的错误时，您可能会发现一些重复项。完全重复项将引发警告 - 删除其中一个重复项...删除哪个重复项并不重要。
