64-bit Ubuntu can not install 32-bit compatible library solution

Ubuntu is different from windows, there is no default integrated 32-bit compatible library on 64-bit Ubuntu, so you need to manually install, the installation method is not difficult, directly in the terminal Execute: sudo apt-get install ia32-libs*.

But today reinstalled Ubuntu (due to misuse of unity collapsed, too lazy to repair directly redo) and found that the implementation of sudo apt-get install ia32-libs* turned out to be wrong! The prompts are as follows: Some packages cannot be installed. If you are using an unstable distribution, this may be because the system is not able to reach the state you requested. In this version, there may be some packages that you need have not been created or they have been moved out of the Incoming directory.

I thought it was a mistake, and later discovered the reason. It turned out that my Ubuntu update server was not synchronized with the official …… so it is OK to transfer the software source to the main server, although it is slower but better than not.
