升级 Linux 内核到指定的版本
- 仅支持
apt 包管理工具
(可自行更改并安装相关依赖，以支持别的包管理器)
- 需要
root 权限，仅在 Deepin V23 下测试过
- 添加可执行权限：
chmod +x ./kernel.sh
- 执行命令：
./kernel.sh 6.1.1 ，复制显示的黄色命令行，粘贴到终端执行
可自行使用指定的 URL：
./kernel.sh 6.1.1 https://cdn.kernel.org/pub/linux/kernel/v6.x/linux-6.1.1.tar.xz
或者 先将安装包下载回来，再执行 ./kernel.sh 6.1.1 安装。
- 当前目录下，生成的日志为
kernel.log
kernel.sh
#!/usr/bin/env bash
