我今天尝试更新我的软件包：
$ sudo apt-get upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
linux-headers-3.16.0-44-generic : Depends: linux-headers-3.16.0-44 but it is not installed
E: Unmet dependencies. Try using -f.
因此，我继续尝试apt-get -f install：
$ sudo apt-get -f install
Reading package lists... Done
Building dependency tree

Correcting dependencies... Done
The following extra packages will be installed:
linux-headers-3.16.0-44
The following NEW packages will be installed:
linux-headers-3.16.0-44

它抱怨说No space left on device。df -Th告诉我有足够的空间：
$ df -h

但是，df -i告诉我/usr已经用完了所有的 inode。
这些是目录及其 inode 用法：
/usr/bin = 2846
/usr/etc = 1
/usr/games = 8
/usr/include = 3204
/usr/lib = 42317
/usr/local = 105
/usr/lost+found = 1
/usr/sbin = 306
/usr/share = 228141
/usr/src = 348704
因此，如果我可以清除/usr/src（其中包含当前和旧内核），我可能可以解决问题。但是，我一直遇到第一个错误：
$ sudo apt-get purge linux-image-3.8.0-35-generic
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
linux-headers-3.16.0-44-generic : Depends: linux-headers-3.16.0-44 but it is not going to be installed
linux-image-extra-3.8.0-35-generic : Depends: linux-image-3.8.0-35-generic but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
关于如何删除旧内核，有什么建议吗？谢谢！
答案1
我的选择和时间都快用完了，所以我尝试了这个并且成功了：
我弄清楚了我正在使用的内核：
$ uname -r
3.16.0-44-generic
我决定将真正旧的内核移到我的外部存储器中：
sudo mv linux-headers-3.8* /media/housni/linux-headers
df -i然后显示大量的 inode 已被释放，因此我快速卸载了那些我知道不需要的标头：
sudo apt-get purge linux-headers-3.8*
之后，我更新了 grub 并重新启动
sudo update-grub2 && sudo shutdown now -r
然后，为了安全起见，我做了一些额外的清理工作，例如清理缓存（sudo apt-get clean）和运行自动删除（sudo apt-get autoremove），现在一切似乎都恢复正常了：）
