Ubuntu下boot分区空间不足无法修复安装新内核的解决

一台Linux虚拟机,当初安装时boot分区仅划分了180MB,后续安装软件的过程中先后安装上了4.4.0-45、4.4.0-47、4.40-51、4.4.0-53、4.4.0-57,在安装后面三个内核时出现了空间不足的问题。后续安装任何软件都提示要运行 apt-get install -f,然后运行此命令则会继续安装4.40-51、4.4.0-53、4.4.0-57这些内核(当前使用中的内核是4.4.0-47),后续安装软件时还被要求安装4.40-104内核。运行apt purge linux-image-4.40-51-generic,仍然提示要运行 apt-get install -f。如下图

The following packages were automatically installed and are no longer required:
linux-headers-4.4.0-31 linux-headers-4.4.0-31-generic linux-headers-4.4.0-45 linux-headers-4.4.0-45-generic linux-headers-4.4.0-51 linux-headers-4.4.0-51-generic linux-headers-4.4.0-53 linux-headers-4.4.0-53-generic linux-image-4.4.0-31-generic
linux-image-4.4.0-45-generic linux-image-4.4.0-51-generic linux-image-4.4.0-53-generic linux-image-extra-4.4.0-31-generic linux-image-extra-4.4.0-45-generic linux-image-extra-4.4.0-51-generic linux-image-extra-4.4.0-53-generic
Use 'sudo apt autoremove' to remove them.
The following additional packages will be installed:
linux-image-4.4.0-45-generic linux-image-4.4.0-51-generic linux-image-4.4.0-53-generic
Suggested packages:
fdutils linux-doc-4.4.0 | linux-source-4.4.0 linux-tools
The following NEW packages will be installed:
linux-image-4.4.0-45-generic linux-image-4.4.0-51-generic linux-image-4.4.0-53-generic
0 upgraded, 3 newly installed, 0 to remove and 247 not upgraded.
2 not fully installed or removed.
Need to get 18.8 MB/57.2 MB of archives.
After this operation, 170 MB of additional disk space will be used.

Abort.
root@vod:/boot# apt install smbclient

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
linux-image-extra-4.4.0-45-generic : Depends: linux-image-4.4.0-45-generic but it is not going to be installed
linux-image-extra-4.4.0-51-generic : Depends: linux-image-4.4.0-51-generic but it is not going to be installed
linux-image-extra-4.4.0-53-generic : Depends: linux-image-4.4.0-53-generic but it is not going to be installed

 

这种情况下,如果上述三个内核已经过时,可以通过dpkg强制删除他们,命令如下(以删除 4.4.0-53内核为例),其他内核也是一样的方法

# dpkg --purge --force-all linux-image-extra-4.4.0-53-generic linux-image-4.4.0-53-generic

经过上述处理后,再运行 apt install 来安装软件应该不会提示运行 apt-get install -f 了
