1. 查看当前内核

rew $ uname -a
Linux rew 4.15.0-42-generic #45~16.04.1-Ubuntu SMP Mon Nov 19 13:02:27 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

2.查看所有内核

rew $ dpkg –get-selections | grep linux
console-setup-linux install
libselinux1:amd64 install
libselinux1:i386 install
linux-base install
linux-firmware install
linux-generic-hwe-16.04 install
linux-headers-4.15.0-42 install
linux-headers-4.15.0-39 install
linux-headers-4.15.0-39-generic install
linux-headers-4.15.0-42-generic install
linux-headers-generic-hwe-16.04 install
linux-image-4.15.0-39-generic install
linux-image-4.15.0-42-generic install
linux-image-generic-hwe-16.04 install
linux-libc-dev:amd64 install
linux-libc-dev:i386 install
linux-modules-4.15.0-39-generic install
linux-modules-4.15.0-42-generic install
linux-modules-extra-4.15.0-39-generic install
linux-modules-extra-4.15.0-42-generic install
linux-sound-base install
pptp-linux install
syslinux install
syslinux-common install
syslinux-legacy install
util-linux install

3.移除多余内核

rew $ sudo apt-get remove
linux-headers-4.15.0-39
linux-headers-4.15.0-39-generic
linux-image-4.15.0-39-generic
linux-modules-4.15.0-39-generic
linux-modules-extra-4.15.0-39-generic

卸载后重新检查:

rew $ dpkg –get-selections | grep linux

状态为deinstall即已经卸载，如果觉得看着不舒服的话可以使用purge连配置文件里一起彻底删除，清理内核列表

rew $ sudo apt-get purge
linux-headers-4.15.0-39
linux-headers-4.15.0-39-generic
linux-image-4.15.0-39-generic
linux-modules-4.15.0-39-generic
linux-modules-extra-4.15.0-39-generic

4.更新系统引导

删除内核后需要更新grub移除失效的启动项

rew $ sudo update-grub #根据情况选择grub/grub2
