Basic Ubuntu knowledge: What about PPA?

Many of the applications installed in Ubuntu have their own PPA, which is easy to upgrade, which brings great convenience to the application. We may not know much about PPA. The following describes how to facilitate software installation. PPA, that is, "PersonalPackageArchives (Personal package archives)" is a service provided by the UbuntuLaunchpad website. It allows individual users to upload software source code, compile and publish it as a binary software package through Launchpad

Many of the applications installed in Ubuntu have their own PPA, which is easy to upgrade, which brings great convenience to the application. We may not know much about PPA. The following describes how to facilitate software installation.

"Personal Package Archives" is a service provided by the Ubuntu Launchpad website, allowing individual users to upload software source code, compile through Launchpad and release it as a binary software package, which serves as an apt/new source for other users to download and update. Every user and team on the Launchpad website can have one or more PPA.

Some PPA are unofficial and may be damaged. It is best to use the official PPA.

#1 add PPAsudo add-apt-repository ppa_name for example, Audacious 2.4.4 release. Run the preceding command to install the latest version Audacious 2.4.4.

Add Audacious PPA

Sudo add-apt-repository ppa: nilarimogard/webupd8 this is set PPA, get key verification software is corrupt

#2. Update to obtain the latest software list.

Sudo apt-get update: Execute the command to upgrade the software package Repository

Sudo apt-get upgrade #3. Finally, install the software.

Sudo apt-get install package_name, as in the preceding example, the installation command is

Sudo apt-get install audacous audacious-plugins. In this way, when we have a software PPA, we can easily add PPA and install the software:

Sudo add-apt-repository PPA name

Sudo apt-get update

Sudo apt-get install software name [Special case] Of course, sometimes we will encounter the following content, such

Deb http://ppa.launchpad.net/gwibber-daily/ppa/ubuntu jaunty main

Deb-src http://ppa.launchpad.net/gwibber-daily/ppa/ubuntu jaunty main at this moment, we open the terminal, enter the command:

Sudo gedit/etc/apt/sources. list copy the above content to the end of the text file, save the file, and exit.

Then, find the "Signing key" (usually below the above content ). You will see the following text,

1024R/72D340A3 (What is this ?) Copy the content following the slash, for example, 72D340A3.

Next, add the key to the system and verify it. For example,

Sudo apt-key adv -- keyserver keyserver.ubuntu.com -- recv-keys 72D340A3 then add the PPA key to the system.

Then, execute

Sudo apt-get update

The sudo apt-get install package name is written in combination with its own experience. For more information, see Ubuntuwiki. If you have any questions, you can leave a message. I will check the changes and give suggestions to the students.
