1. 去https://www.kernel.org查看最新稳定内核版本

2. 打开https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4.6/ （假设此时最新版是5.4.6）

   Build for amd64 succeeded (see BUILD.LOG.amd64):
   linux-headers-5.4.6-050406_5.4.6-050406.201912211140_all.deb
   linux-headers-5.4.6-050406-generic_5.4.6-050406.201912211140_amd64.deb
   linux-headers-5.4.6-050406-lowlatency_5.4.6-050406.201912211140_amd64.deb
   linux-image-unsigned-5.4.6-050406-generic_5.4.6-050406.201912211140_amd64.deb
   linux-image-unsigned-5.4.6-050406-lowlatency_5.4.6-050406.201912211140_amd64.deb
   linux-modules-5.4.6-050406-generic_5.4.6-050406.201912211140_amd64.deb
   linux-modules-5.4.6-050406-lowlatency_5.4.6-050406.201912211140_amd64.deb

3. wget下载包名里没有lowlatency的deb包 ， sudo dpkg -i ***.deb 依次安装 ：

   linux-headers-5.4.6-050406_5.4.6-050406.201912211140_all.deb
   linux-headers-5.4.6-050406-generic_5.4.6-050406.201912211140_amd64.deb
   linux-modules-5.4.6-050406-generic_5.4.6-050406.201912211140_amd64.deb
   linux-image-unsigned-5.4.6-050406-generic_5.4.6-050406.201912211140_amd64.deb

4. 查看已安装内核

   dpkg -l|grep linux-image | awk '{print $2}'

5. 删除旧内核

   apt purge -y 

6. 更新grub 然后重启

   update-grub
   reboot

7. 检查一下是否更换成功

   uname -r
