尽管 /usr 中使用了 100% 的 inode，我如何删除旧内核？

Question

我今天试图更新我的软件包：

$ 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.

所以，我继续尝试apt-get -f install：

$ sudo apt-get -f install
Reading package lists... Done
Building dependency tree       
Reading state information... Done
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
0 upgraded, 1 newly installed, 0 to remove and 3 not upgraded.
3 not fully installed or removed.

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

$ df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda6       3.3G  2.5G  571M  82% /
udev            2.0G     0  2.0G   0% /dev

tmpfs           5.0M  8.0K  5.0M   1% /run/lock
/dev/sda7       9.3G  7.6G  1.3G  87% /usr
/dev/sda8       188G  176G  3.0G  99% /home
/dev/sda1       945M  394M  487M  45% /boot
/dev/sda9       256G  9.6G  233G   4% /var

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的任何建议？谢谢！

Answer 1

我的选择和时间都用完了，所以我尝试了这个，它奏效了：

我想出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，因此我迅速卸载了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

然后我做了一些额外的清理工作，比如清理我的缓存 ( sudo apt-get clean) 并运行 autoremove ( sudo apt-get autoremove) 只是为了安全，现在一切似乎都恢复正常了:)
