【64位ubuntu12.04 运行adb出错 及 终于解决无法安装ia32-libs】
运行adb显示无此文件或者目录，路径配置正确。
错误：
bash: /home/zhong/java/adt-bundle-linux-x86_64-20140321/sdk/platform-tools/adb: 没有那个文件或目录
查看adb文件属性：
file /home/zhong/java/adt-bundle-linux-x86_64-20140321/sdk/platform-tools/adb
/home/zhong/java/adt-bundle-linux-x86_64-20140321/sdk/platform-tools/adb: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV),
dynamically linked (uses shared libs), for GNU/Linux 2.6.8, not stripped
所以32为软件运行在64ubuntu上，需要安装32为运行库。
解决方法：
sudo apt-get install ia32-libs
如果出错：
下列软件包有未满足的依赖关系：
ia32-libs : 依赖: ia32-libs-multiarch
E: 无法修正错误，因为您要求某些软件包保持现状，就是它们破坏了软件包间的依赖关系。
这是因为在安装的过程中，由于一些软件包的缺失，造成此问题。解决的方法很简单，是因为软件包的源出了问题。修改源即可。
