andlinux的ubuntu版本升級 -- 9.04到10.04

  andlinux現在的unbuntu版本是jaunty(9.04)，該版本官方已經不支持了，所以apt-get源被移除了，只要升級到lucid(10.04)就可以了。按以下步驟：
   要先升級到karmic(9.10)，然後才能升級到lucid(10.04)。(因爲karmic 9.10也很快就不支持了，所以還是升級到lucid 10.04版本好）
    
   先升級到karmic(9.10)：
   （1）修改/etc/apt/sources.list文件，全部替換如下：
   deb http://mirrors.163.com/ubuntu/ karmic main universe restricted multiverse
   deb-src http://mirrors.163.com/ubuntu/ karmic main universe restricted multiverse
   deb http://mirrors.163.com/ubuntu/ karmic-security universe main multiverse restricted
   deb-src http://mirrors.163.com/ubuntu/ karmic-security universe main multiverse restricted
   deb http://mirrors.163.com/ubuntu/ karmic-updates universe main multiverse restricted
   deb http://mirrors.163.com/ubuntu/ karmic-proposed universe main multiverse restricted
   deb-src http://mirrors.163.com/ubuntu/ karmic-proposed universe main multiverse restricted
   deb http://mirrors.163.com/ubuntu/ karmic-backports universe main multiverse restricted
   deb-src http://mirrors.163.com/ubuntu/ karmic-backports universe main multiverse restricted
   deb-src http://mirrors.163.com/ubuntu/ karmic-updates universe main multiverse restricted
   （2）在命令行執行sudo apt-get update
   （3）在命令行執行sudo upgrade
   （4）重啓linux
    
   然後再升級到lucid(10.04)，步驟如下：
   （1）修改/etc/apt/sources.list文件，全部替換如下：
   deb http://mirrors.163.com/ubuntu/ lucid main universe restricted multiverse
   deb-src http://mirrors.163.com/ubuntu/ lucid main universe restricted multiverse
   deb http://mirrors.163.com/ubuntu/ lucid-security universe main multiverse restricted
   deb-src http://mirrors.163.com/ubuntu/ lucid-security universe main multiverse restricted
   deb http://mirrors.163.com/ubuntu/ lucid-updates universe main multiverse restricted
   deb http://mirrors.163.com/ubuntu/ lucid-proposed universe main multiverse restricted
   deb-src http://mirrors.163.com/ubuntu/ lucid-proposed universe main multiverse restricted
   deb http://mirrors.163.com/ubuntu/ lucid-backports universe main multiverse restricted
   deb-src http://mirrors.163.com/ubuntu/ lucid-backports universe main multiverse restricted
   deb-src http://mirrors.163.com/ubuntu/ lucid-updates universe main multiverse restricted
   （2）在命令行執行sudo apt-get update
   （3）在命令行執行sudo upgrade
   （4）重啓linux
