遇到了Linux新的内核启动卡死，老内核正常运行，索性就启动不了内核进行删除。
1. 查看当前运行的内核
在终端运行以下命令：
uname -r
会得到下面这样的信息：
5.15.0-97-generic
2. 列出所有安装的内核
列出所有已安装的内核：
dpkg --list | grep linux-image
这个命令将显示所有已安装的Linux内核包，如下所示：
rc linux-image-5.15.0-100-generic 5.15.0-100.110~20.04.1 amd64 Signed kernel image generic
rc linux-image-5.15.0-101-generic 5.15.0-101.111~20.04.1 amd64 Signed kernel image generic
rc linux-image-5.15.0-102-generic 5.15.0-102.112~20.04.1 amd64 Signed kernel image generic
ii linux-image-5.15.0-105-generic 5.15.0-105.115~20.04.1 amd64 Signed kernel image generic
rc linux-image-5.15.0-67-generic 5.15.0-67.74~20.04.1 amd64 Signed kernel image generic
rc linux-image-5.15.0-84-generic 5.15.0-84.93~20.04.1 amd64 Signed kernel image generic
rc linux-image-5.15.0-86-generic 5.15.0-86.96~20.04.1 amd64 Signed kernel image generic
rc linux-image-5.15.0-87-generic 5.15.0-87.97~20.04.1 amd64 Signed kernel image generic

rc linux-image-5.15.0-92-generic 5.15.0-92.102~20.04.1 amd64 Signed kernel image generic
rc linux-image-5.15.0-94-generic 5.15.0-94.104~20.04.1 amd64 Signed kernel image generic
ii linux-image-5.15.0-97-generic 5.15.0-97.107~20.04.1 amd64 Signed kernel image generic
ii linux-image-generic-hwe-20.04 5.15.0.105.115~20.04.1 amd64 Generic Linux kernel image
3. 删除内核
使用apt-get或apt命令删除不需要的内核。比如 linux-image-5.15.0-105-generic的内核，可以使用：
sudo apt-get purge linux-image-5.15.0-105-generic
4. 更新引导加载器
完成内核的删除后，更新GRUB配置以确保启动加载器的菜单被更新：
sudo update-grub
5. 重启系统
最后，重启系统以确认更改：
sudo reboot
