![尽管 /usr 中的 inode 使用率为 100%,我该如何删除旧内核?](https://linux22.com/image/874644/%E5%B0%BD%E7%AE%A1%20%2Fusr%20%E4%B8%AD%E7%9A%84%20inode%20%E4%BD%BF%E7%94%A8%E7%8E%87%E4%B8%BA%20100%25%EF%BC%8C%E6%88%91%E8%AF%A5%E5%A6%82%E4%BD%95%E5%88%A0%E9%99%A4%E6%97%A7%E5%86%85%E6%A0%B8%EF%BC%9F.png)
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

The following extra packages will be installed:

告诉我有足够的空间:

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:)
