Ubuntu 14.04 ADB does not have that file or directory

Just installed 64-bit system, Ubuntu14.04, build jdk,android environment, the Android SDK copied over, the inside of the ADB and other commands can not be used.
Error message: android-sdk-linux_86/platform-tools/adb: There is no file or directory.
Goolge to the solution: because it is a 64bit system, and the Android SDK only 32bit programs, need to install ia32-libs, in order to use.

Run the following command:

$ sudo apt-get install Ia32-libs

[sudo] password for Rengh:
Reading Package List ... Complete

There is no package ia32-libs available now, but it is referenced by other packages.
This may mean that the missing package may have been discarded,
Or can only be found in other publishing sources
However, the following packages replace it:
LIB32Z1 lib32ncurses5 lib32bz2-1.0

E: Package Ia32-libs not available for installation candidate

Depressed!!!!

Re-Google Solutions:

sudo apt-get install G++-multilib
sudo apt-get install libncurses5:i386
sudo apt-get install libc6:i386 libgcc1:i386 gcc-4.6-base:i386 libstdc++5:i386 libstdc++6:i386

OK, get it done! 14.04 It's so complicated, record it first!
