1、ubuntu下面修改更新源 sudo gedit /etc/apt/sources.list
2、編譯內核：
(1) cd 到/usr/src/下，解壓下載的內核源代碼包
(2) make mrproper 清理生成的文件(貌似對第一次編譯內核沒有必要)
(3) make menuconfig (如果不行，需要安裝libncurses5-dev，使用命令 sudo apt-get install
libncurses5-dev，搜索相關文件使用sudo apt-cache search
文件名)
我在安裝時遇到問題：The following packages have unmet dependencies:
libncurses5-dev : Depends: libncurses5 (= 5.9-4) but 5.9-10ubuntu1 is to be installed
Depends: libtinfo-dev (= 5.9-4) but it is not going to be installed
Depends: ncurses-bin (= 5.9-4) but 5.9-10ubuntu1 is to be installed
解決是在http://packages.ubuntu.com/網站上直接下載了 libncurses5、libtinfo-dev和ncurses-bin的5.9.4版本，然後用dpkg命令進行了安裝。
(4)
make bzImage -jn (n為cpu個數)
(5)
make modules
(6)make
modules_install
(7)make
install
