总的步骤
- 查询当前内核版本: uname -a
- 列出所有内核: dpkg –get-selections | grep linux-image
- 删除老的内核: sudo apt-get remove linux-image-xxxx
Example
flying-bird@flyingbird:~$ dpkg --get-selections | grep linux-image linux-image-3.13.0-33-generic deinstall linux-image-3.13.0-34-generic deinstall linux-image-3.13.0-35-generic deinstall linux-image-3.13.0-36-generic deinstall linux-image-3.13.0-37-generic deinstall linux-image-3.13.0-39-generic deinstall linux-image-3.13.0-40-generic deinstall linux-image-3.13.0-43-generic deinstall linux-image-3.13.0-44-generic deinstall linux-image-3.13.0-46-generic deinstall linux-image-3.13.0-48-generic deinstall linux-image-3.13.0-49-generic deinstall linux-image-3.13.0-53-generic deinstall linux-image-3.13.0-55-generic deinstall linux-image-3.13.0-57-generic deinstall linux-image-3.13.0-58-generic deinstall linux-image-3.13.0-85-generic deinstall linux-image-3.13.0-86-generic deinstall linux-image-3.13.0-87-generic deinstall linux-image-3.13.0-93-generic install linux-image-3.2.0-24-generic-pae deinstall linux-image-3.2.0-67-generic-pae install linux-image-4.4.0-34-generic deinstall linux-image-extra-3.13.0-33-generic deinstall linux-image-extra-3.13.0-34-generic deinstall linux-image-extra-3.13.0-35-generic deinstall linux-image-extra-3.13.0-36-generic deinstall linux-image-extra-3.13.0-37-generic deinstall linux-image-extra-3.13.0-39-generic deinstall linux-image-extra-3.13.0-40-generic deinstall linux-image-extra-3.13.0-43-generic deinstall linux-image-extra-3.13.0-44-generic deinstall linux-image-extra-3.13.0-46-generic deinstall linux-image-extra-3.13.0-48-generic deinstall linux-image-extra-3.13.0-49-generic deinstall linux-image-extra-3.13.0-53-generic deinstall linux-image-extra-3.13.0-55-generic deinstall linux-image-extra-3.13.0-57-generic deinstall linux-image-extra-3.13.0-58-generic deinstall linux-image-extra-3.13.0-85-generic deinstall linux-image-extra-3.13.0-86-generic deinstall linux-image-extra-3.13.0-87-generic deinstall linux-image-extra-3.13.0-93-generic install linux-image-extra-4.4.0-34-generic deinstall flying-bird@flyingbird:~$ uname -a Linux flyingbird 3.13.0-93-generic #140-Ubuntu SMP Mon Jul 18 21:20:08 UTC 2016 i686 i686 i686 GNU/Linux flying-bird@flyingbird:~$ sudo apt-get remove linux-image-3.2.0-67-generic-pae [sudo] password for flying-bird: Reading package lists...
