方法一:
sudo -i
cd /etc/apt/sources.list.d
echo "deb http://archive.ubuntu.com/ubuntu/ raring main restricted universe multiverse" >ia32-libs-raring.list
apt-get update
apt-get install ia32-libs




PS:這種方法肯定能安裝上ia32-libs，但由於新增的是13.04的源，所以有沒有混淆暫時不清楚，
網上也有很多用新立德軟體包管理器這樣做；夠狠，你就這麼幹。也可以這麼安裝了ia32-libs後，
把/etc/apt/sources.list.d目錄下的ia32-libs-raring.list刪掉，然後再sudo apt-get update








方法二:
切換至中科大的源 http://uestc.edu.cn
 然後apt-get update
接著apt-get install ia32-libs
如果終端出現:

E: 有幾個軟體包無法下載，您可以執行 apt-get update 或者加上 --fix-missing 的選項再試試？*

自己去網上搜索這三個包,然後安裝.
或者使用以下網址:


https://packages.debian.org/wheezy/i386/libgphoto2-port0/download


https://packages.debian.org/wheezy/i386/libgphoto2-2/download


https://launchpad.net/ubuntu/raring/i386/libgd2-xpm/2.0.36~rc1~dfsg-6.1ubuntu1


安裝後再執行apt-get install ia32-libs

沒有意外應該裝上了.
