我使用命令安装了内核的 Linux 头文件：
sudo apt-get install linux-headers-`uname -r`
在文件夹中
/usr/src/linux-headers-2.6.32-21-generic
全部文件的链接已损坏。
示例：文件 linux-headers-2.6.32-21/crypto 有断开的链接指向 ../linux-headers-2.6.32-21/crypto。
输出

我该如何修复这个问题？（我想要没有断开链接的头文件）。
答案1
目录中缺少的文件/usr/src/linux-headers-2.6.32-21是假如通过包装Linux 标头-2.6.32-21。要获取它们，请尝试安装该包。
如果您想从命令行安装它，请运行：
sudo apt-get update && sudo apt-get install linux-headers-2.6.32-21
（该apt-get update部分将有助于确保系统根据有关哪里有哪些软件包以及哪些版本可用的正确且一致的信息来安装软件包。）
