安装软件包时“设备上没有剩余空间”，但我还有空间

Question

无论是通过更新管理器还是通过终端，我都出错了。

当我尝试sudo apt-get update && sudo apt-get upgrade：

Fetched 1,024 kB in 20s (51.0 kB/s) 
Reading package lists... Done

You might want to run 'apt-get -f install' to correct these. 
The following packages have unmet dependencies: linux-headers-generic : 
Depends: linux-headers-3.13.0-29-generic but it is not installed 
E: Unmet dependencies. Try using -f.

当我尝试时sudo apt-get -f install：

当我打开 Ubuntu 软件中心时，我得到以下文本：

无法安装新软件，因为当前安装的软件有问题。您现在要修复此问题吗？

我可以选择“修复”或“取消”。如果我点击“修复”，我会收到以下错误：

磁盘已满错误很奇怪，因为我的磁盘都没有满。我知道这一点，因为当我运行时df，我得到以下信息：

这个时候我该怎么办？提前致谢。

在 unix 文件系统上，文件和目录有两个部分：inode和数据。

inode 中存储有关文件的信息，例如权限、所有者、更改时间、访问时间等。

inode 的总数是有限的，因此No space left on device即使磁盘不是很满，如果达到此限制，您也可以获得。

用：

df -i

查看inode，如果你得到100% forIUse和 0 IFree，这意味着你有很多小文件。

例如，如果您有 20 亿个大小为 1 字节的文件，您可能会达到 inode 限制，但您的磁盘可能不会完全满。

如果是这种情况，请尝试删除更多文件，而不是重做apt-get update。
