Let's talk about Ubuntu8.04HardyLTS software source settings

Article Title: Let's talk about Ubuntu8.04HardyLTS software source settings again. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

Preface: Xiao F browsed many domestic and foreign websites and read many articles about Software source settings. He found many articles have misunderstandings about Software source settings, in order to allow new people to smoothly enter the family of Ubuntu, Xiao F made this article to introduce the software source settings in detail.

1. What is Software Sources?

In Ubuntu, a software source is a collection of addresses that can obtain software. The address can be a website, a CD, or a directory on a hard disk. There is a "software warehouse" on the software source, and various software are stored in the software warehouse. When you need a software, you can automatically download it and install it using a new tool (such as synaptic, apt-get, or aptitude.

2. What convenience can I get when Software Sources are set up?

Routine software installation or update is performed by obtaining software packages from the software source. Setting software sources allows you to obtain important security updates in a timely manner to solve security risks, or fix known problems to make it easier to use. Setting software sources can also speed up the above operations and save valuable time.

3. I am a newbie. I will not set it. Is there a simple graphical interface for setting?

The Ubuntu System-System management (Administration) Menu provides the Software source setting (Software Sources) program on the graphical interface, this is not enough! (For more information about the setting method, see the following link)

4. Correct settings!

Before modifying the settings, back up the original settings. This step seems redundant. It is actually a good habit and is conducive to the recovery of configuration errors. Backup method: press Alt + F2, and then enter gksu cp/etc/apt/sources. list/etc/apt/sources. list-backup. Press enter and enter your password.

Then open the setup program: System-System management-Software Sources ). On the first tab, click the menu on the right of "Download From" and select "Others... (Others ...)". In the displayed window, click Select Best Server )". The system will automatically ping the servers in the official server list and select the fastest server!

Press Alt + F2 to open "Run Application" and enter gksu gedit/etc/apt/sources. list. Enter your password if you are prompted. Move the cursor to the end of the file.

5. Why should I set up so many foreign sources?

Ubuntu projects are jointly maintained by fans around the world, so it is difficult to synchronize updates to server files. As Ubuntu's main server is located in Europe, the project team is located in Norway, while English is the most widely used language among Ubuntu users, therefore, the latest version will soon be released to the European main source and US source of Ubuntu. At the same time, Ubuntu update sources in China often have software packages missing. Therefore, we recommend that you set up official sources in Europe and the United States.

6. Is the higher the source speed?

Unfortunately, Ubuntu software management programs do not have the ability to automatically determine the fastest source. Therefore, no matter how many sources you have set, Ubuntu only finds the source that provides the corresponding software package download and connects to download in the order of the source list. Therefore, we asked Ubuntu to automatically find the fastest source at the time of configuration, and then add the source that may be supplemented to the end. On the contrary, setting too many sources reduces the update speed (apt-get update.
