ubuntu升级内核

The simplest set of instructions I always used for kernel upgrade / downgrade are by ubuntuforums.org user by the name of lykwydchykyn (url modified by me for this post):

Go here: http://kernel.ubuntu.com/~kernel-ppa/mainline/ Download 3 (maybe 4) debs to a folder somewhere:

linux-headers-VERSION-NUMBER_all.deb
linux-headers-VERSION-NUMBER_amd64.deb
linux-image-VERSION-NUMBER_amd64.deb
linux-image-extra-VERSION-NUMBER_amd64.deb   # if available

Install the debs with whatever package manager front-end you use (is gdebi still around?), or use these commands:

cd /path/to/folder/where/you/put/the/debs
sudo dpkg -i *.deb

我下载了如下３个包：(版本号的第２位如果是偶数代表稳定版，基数代表开发版）
