制作apt-get源

1.拷貝deb包：sudo cp /var/cache/apt/archives/* /home/apt-get/packages/Natty/
2.安裝工具包:sudo apt-get install dpkg-dev
3.進入指定目錄，生成軟體包依賴資訊檔案：
cd /home/apt-get/packages
sudo dpkg-scanpackages Natty /dev/null | gzip >Natty/Packages.gz
4.将位址加入更新源清單檔案:
sudo vim /etc/apt/sources.list
deb file:///home/apt-get/packages/  Natty/
deb http://10.63.201.122:18081/apt-get/packages Natty/
5.更新軟體包清單
sudo apt-get update
