Linux多个不同版本内核卸载管理

Ubuntu删除多余的内核

1. 查看当前的内核

   root@azhal:~## uname -a
   Linux azhal 5.11.16-xanmod1-cacule #0~git20210421.d9591de SMP PREEMPT Wed Apr 21 17:44:04 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

2. 查看当前系统中所有的内核

   root@azhal:~## dpkg --get-selections |grep linux
   binutils-x86-64-linux-gnu                       install
   console-setup-linux                             install
   libselinux1:amd64                               install
   libselinux1-dev:amd64                           install
   linux-base                                      install
   linux-firmware                                  install
   linux-headers-5.11.16-xanmod1-cacule            install
   linux-image-5.11.16-xanmod1-cacule              install
   linux-image-5.4.0-72-generic                    install
   linux-image-generic                             install
   linux-libc-dev:amd64                            install
   linux-modules-5.4.0-72-generic                  install
   linux-modules-extra-5.4.0-72-generic            install
   linux-xanmod-cacule                             install
   util-linux                                      install
