Ubuntu 12.04：为什么 apt-get 更新失败？

Question

我无法为 Ubuntu 12.04 安装任何软件包。即使在清除以下文件后：

/var/lib/dpkg/lists/partial/* /var/lib/dpkg/lists/*
/var/cache/apt/*

更改了存储库并尝试apt-get clean了 Ubuntu 论坛提供的所有其他解决方案。没有任何效果，我之前遇到过同样的问题并重新安装了 Ubuntu。但这不是永久的解决方案。

希望 Ubuntu 开发人员绝对应该知道解决此问题的快速解决方法。对于所有 Ubuntu 用户来说，这是一个无法解决的非常普遍的问题。请创建一个全球常见问题解答来解决这个问题。

只需删除 /var/lib/apt/lists 目录的内容：

sudo rm -fR /var/lib/apt/lists/*

然后运行：

sudo apt-get update
