当/boot已满时,如何删除旧内核/安装新内核?

,

问题描述

我知道这个问题之前已被问过很多次了,不过对我而言,我猜它只是有点不同。

# df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda3       224G  5.2G  208G   3% /
udev            1.9G  4.0K  1.9G   1% /dev

/dev/sda6       1.9G  514M  1.3G  29% /tmp

我的启动分区已满。

当前内核:

# uname -r
3.2.0-35-generic

所有内核:

# dpkg --list | grep linux-image
ii  linux-image-3.2.0-32-generic    3.2.0-32.51                         Linux kernel image for version 3.2.0 on 64 bit x86 SMP
ii  linux-image-3.2.0-34-generic    3.2.0-34.53                         Linux kernel image for version 3.2.0 on 64 bit x86 SMP
ii  linux-image-3.2.0-35-generic    3.2.0-35.55                         Linux kernel image for version 3.2.0 on 64 bit x86 SMP
iF  linux-image-3.2.0-37-generic    3.2.0-37.58                         Linux kernel image for version 3.2.0 on 64 bit x86 SMP
iF  linux-image-3.2.0-38-generic    3.2.0-38.60                         Linux kernel image for version 3.2.0 on 64 bit x86 SMP
iU  linux-image-generic             3.2.0.37.45                         Generic Linux kernel image

所以我想用以下方法删除3.2.0.32通用内核:

# sudo apt-get purge linux-image-3.2.0-32-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-generic : Depends: linux-headers-generic (= 3.2.0.37.45) but 3.2.0.38.46 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

没有成功。

当我尝试apt-get -f install时,它也会失败:

# apt-get -f install

The following packages were automatically installed and are no longer required:
  linux-headers-3.2.0-34 linux-headers-3.2.0-35 linux-headers-3.2.0-34-generic linux-headers-3.2.0-35-generic
Use 'apt-get autoremove' to remove them.
The following extra packages will be installed:

真的很感激任何帮助。

更新:我做了:

sudo rm /boot/*-3.2.0-32-generic /boot/*-3.2.0-34-generic

之后,apt-get -f install出现以下问题:

最佳解决思路

当内核过期时,您不能使用apt-get。

cd /boot
sudo rm *-2.6.35-6.9-generic
sudo rm *-3.16.0-23-generic

使用ls查看文件夹中的内容,删除最旧的一两个

sudo apt-get -f install

然后你将apt-get清除为中

sudo apt-get purge linux-image-3.2.0-32-generic linux-image-3.2.0-34-generic

或者继续使用rm。

当你被finsihed时,你也应该sudo update-grub

次佳解决思路

显然,这有效:

sudo apt-get autoremove 

根据apt-get man-page:

autoremove is used to remove packages that were automatically installed to satisfy dependencies for other packages and are now no longer needed.

3.16.0-39是我试图安装的,但因为/boot已满而失败。 3.16.0-38是我目前的版本。你可以看到-38被跳过了。

server:~$ uname -r
3.16.0-38-generic
server:~$ sudo apt-get autoremove 
[sudo] password for mikeb: 
Reading package lists... Done
Building dependency tree       
Reading state information... Done
The following packages will be REMOVED:
  linux-headers-3.16.0-30 linux-headers-3.16.0-30-generic
  linux-headers-3.16.0-31 linux-headers-3.16.0-31-generic
  linux-headers-3.16.0-33 linux-headers-3.16.0-33-generic
  linux-headers-3.16.0-34 linux-headers-3.16.0-34-generic
  linux-headers-3.16.0-36 linux-headers-3.16.0-36-generic
  linux-headers-3.16.0-39 linux-headers-3.16.0-39-generic
  linux-image-3.16.0-30-generic linux-image-3.16.0-31-generic
  linux-image-3.16.0-33-generic linux-image-3.16.0-34-generic
  linux-image-3.16.0-36-generic linux-image-3.16.0-39-generic
  linux-image-extra-3.16.0-30-generic linux-image-extra-3.16.0-31-generic
  linux-image-extra-3.16.0-33-generic linux-image-extra-3.16.0-34-generic
  linux-image-extra-3.16.0-36-generic linux-image-extra-3.16.0-39-generic
0 upgraded, 0 newly installed, 24 to remove and 0 not upgraded.

第三种解决思路

在终端中,执行以下命令:

dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d' | xargs sudo apt-get purge

此命令列出所有当前安装的Linux内核,然后选择当前未使用的所有内核并将其删除。

第四种思路

dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d' | xargs sudo apt-get -y purge

如果在没有“sudo apt-get -y purge”的情况下运行上述命令与您的linux-libc-dev:amd64匹配,则可以在正则表达式中添加分号以不包含它:

dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ :]*\).*/\1/;/[0-9]/!d' | xargs

现在只需确保它看起来不错并添加“sudo apt-get -y purge”
