[Turn] Add-apt-repository

Perhaps you have already noticed, when we introduce the software, in the installation of this block generally provide PPA source installation, this is a quick and easy way to install the software, but for some novice, is not very familiar with the PPA, we will introduce in detail below.

# Let's take a look at the definition of PPA:

The PPA, known as the Personal package Archives (Personal packages Archive), is a service provided by the Ubuntu Launchpad website and is certainly not limited to Launchpad. It allows individual users to upload software source code, compile it via Launchpad and publish it as a binary package, as a new source of apt/for other users to download and update. Each user and team on the Launchpad website can have one or more ppa.

Usually the software in the PPA source is not in the official source, or is the latest version of the software. The advantage of using PPA over the installation of the DEB package is that once the software is updated, the command can be upgraded directly to the new version via sudo apt-get upgrade.

# How to install the software via the PPA Source:

Usually we can search through Google to some of the common software PPA source, the usual search method is the software name keyword + PPA, or can also go directly to launchpad.net search, after the search we can directly with the sudo apt-add-repository command Added the PPA source to the source list.

For example, FireFox PPA Source: Https://launchpad.net/~ubuntu-mozilla-daily/+archive/ppa, we can find here Ppa:ubuntu-mozilla-daily/ppa , and then we add the source to the sources list using the following command.

sudo apt-add-repository Ppa:ubuntu-mozilla-daily/ppa

Then we'll find the FireFox 4.0 package name for the current Ubuntu version from the Packages list below, update the source and install:

Sduo apt-get Update
sudo apt-get install firefox-4.0

In fact, in addition to the command-line approach, Ubuntu also provides a GUI interface of the third-party source management tools, this is not detailed. In addition, Ubuntu-tweak also contains a large number of third-party sources, you can install third-party software by one click, it is highly recommended for novice installation.
