How to enable the 32-bit support function of 64-bit Ubuntu

Most people who use Ubuntu/Debian-based releases prefer 64-bit systems, right? This is because a 64-bit system can give full play to all the performance of your hardware. It enables you to use more complex software with more limited memory resources, and it is really quick to use, you don't have to wait for a long time for every small task. Currently, 32-bit has only one advantage, that is, there are not many compatibility issues. Every JAVA update is confusing because most users cannot obtain the required library files. In the past, many other software and drivers were not 64-bit.

Therefore, if you have a 64-bit architecture system, and you can use the previous support, including the driver, 64-bit version, and any software you need. This avoids all problems, right? Is there a method that allows you to use 32-bit software in a 64-bit system? You can simply read this article and follow it. If you have Ubuntu/Debian 13.10 or later, you need to install a base package called ia32-libs. Now, this package has been deprecated, so you must install it manually.

The following command can be run on Ubuntu/Debian 13.10 or higher.

Step 1: confirm that you have a 64-bit Kernel

You can open the terminal and enter:

1. Dpkg -- print-architecture

You will see the following content:

1. Amd64

This indicates that you already have a 64-bit architecture kernel.

Step 2: confirm that you have enabled the multi-architecture Support feature

(Multi-architecture support allows you to use a 32-bit database with a 64-bit database .)

Input:

1. Dpkg -- print-foreign-ubuntures

The output is:

1. I386

If you do not have multiple architectures, you need to open them.

Step 2: Enable multi-architecture support.

Input:

1. Sudo dpkg -- add-architecture i386
2. Sudo apt-get update

Then download the update and run it.

Then you need to enter:

1. Sudo apt-get dist-upgrade

It checks whether the library file you already have has an updated version.

If yes, it will ask if you need to update (y/n ).

In this way, you have successfully installed 32-bit support for your 64-bit system.
