The software warehouse is the server where the package is stored

If you've ever been a user of Windows or Mac OS, you may be accustomed to searching the internet for a program (and often a program's installation file), downloading it, and installing it. You may be familiar with the software published in CD-ROM format. These released CDs often feature automatic running features to help you install the software. For the Open source system (http://www.aliyun.com/zixun/aggregation/13835.html ">ubuntu GNU"), a part of the software is also published in this form. But most of the software is a program that has been developed and packaged.

For systems like Ubuntu, most software is packaged with a. Deb (or. rpm) file. Such packages include the programs and libraries you need. These packages can be downloaded from the Internet or obtained from the CD (the Ubuntu CD is full of this stuff). "A software warehouse is a server that stores packages." You can usually get these packages through tools such as synaptic.

These tools can list all the packages you have installed (from your system core to your most commonly used programs, including all installed libraries), and they can also list the packages that are available in the current configuration of the software repository. They can also help you search for vague ranges such as "image editors."

These tools provide a simple and centralized approach to software installation while also helping software publishers to centrally upgrade published software.

In Ubuntu, you usually want to have at least an Ubuntu software repository (probably on the installation CD). But getting other repositories (not from Ubuntu) is not uncommon.

You know, "Most of the tools you want to use in Ubuntu are already in the Ubuntu software repository." This is important. You can search the Internet for other packages, or source code, but it will be more difficult to install to Ubuntu. And most of the time, the software doesn't really integrate well with your system.

So now you should know: don't endlessly search the internet for shared or free software that has a backdoor. Linux already has a lot of packaged software for you to choose from.
