Ubuntu 下安装最新稳定版Linux内核kernel

本文将会讲述如何在Ubuntu 16.04 LTS 系统下安装最新版的linux内核。 在安装最新版内核前,需要需要考虑系统宕机风险,所以通常情况下,我们最好安装最新的稳定版本。

下面我们通过两种方法来在ubuntu系统下安装最新版的linux内核。

方法一:通过apt安装最新linux版本内核

1# 查看当前系统的linux内核版本

执行下面的命令:

$uname -mrs

命令输出如下:

Linux 4.4.0-62-generic x86_64

2# 查看当前可用的最新版本的linux 内核

执行下面的命令:

$ apt-cache search linux-generic

命令输出如下:

linux-generic - Complete Generic Linux kernel and headers
 linux-generic-lts-utopic - Complete Generic Linux kernel and headers (dummy transitional package)
 linux-generic-lts-vivid - Complete Generic Linux kernel and headers (dummy transitional package)
 linux-generic-lts-wily - Complete Generic Linux kernel and headers (dummy transitional package)

4# 重启ubuntu 系统

$ sudo reboot

5# 查看当前系统的最新linux内核版本

$ uname -mrs

方法二:通过下载最新内核deb包安装内核

1# 首先访问kernel.org 官方网站确定当前最新的稳定版本号
2# 从ubuntu kernel官方下载该版本kernel http://kernel.ubuntu.com/~kernel-ppa/mainline/
使用wget命令来下载内核deb包:

$wget  http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.12.8/linux-image-4.12.8-041208-generic_4.12.8-041208.201708161815_amd64.deb
$ wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.12.8/linux-headers-4.12.8-041208_4.12.8-041208.201708161815_all.deb

3# 安装下载的.deb包

$ sudo dpkg -i *.db

4# 重启系统

$ sudo reboot
