How to install PPA (Personal Package Archive) and languages in Ubuntu 14.04/14.10. Learn how to install and remove softwares on Linux Ubuntu.
Personal Package Archives (PPAs) are software repositories designed for Ubuntu users and are easier to install than other third-party repositories. Always remember to only add software repositories from sources that you trust.
Third-party software repositories are not checked for security or reliability by Ubuntu members, and may contain software which is harmful to your computer.
Install a PPA
- On the PPA’s overview page, look for the heading Adding this PPA to your system. Make a note of the PPA’s location, which should look similar to: ppa:mozillateam/firefox-next.
- Click the Ubuntu Software Center icon in the Launcher, or search for Software Center in the Dash.
- When the Software Center launches, click Edit ▸ Software Sources
- Switch to the Other Software tab.
- Click Add and enter the ppa: location.
- Click Add Source. Enter your password in the Authenticate window.
- Close the Software Sources window. Ubuntu Software Center will then check your software sources for new software.
Install languages
When you install Ubuntu, the language you select at installation gets installed together with English, but you can add further languages.
- Click the icon at the very right of the menu bar and select System Settings.
- In the Personal section, click Language Support.
- Click Install / Remove Languages…. The Installed Languages window lists all the available languages, with the currently installed languages checked.
- Check the languages you want to install, and uncheck those currently installed languages you want to remove.
- Click Apply Changes.
Please note that to install languages on your Ubuntu 14.04 PC, administrative privileges are required. Enter your password, or the password for the requested administrator account.
Install additional software
The Ubuntu development team has chosen a default set of applications that we think makes Ubuntu very useful for most day-to-day tasks. However, you will certainly want to install more software to make Ubuntu more useful to you.
- Connect to the Internet using a wireless or wired connection.
- Click the Ubuntu Software Center icon in the Launcher, or search for Software Center in the Dash.
- When the Software Center launches, search for an application, or select a category and find an application from the list.
- Select the application that you are interested in and click Install.
- You will be asked to enter your password. Once you have done that the installation will begin.
- The installation usually finishes quickly, but could take a while if you have a slow Internet connection.
- A shortcut to your new app will be added to the Launcher. To disable this feature, uncheck View ▸ New Applications in Launcher.
Remove an application
The Ubuntu Software Center helps you to remove software that you no longer use.
- Click the Ubuntu Software Center icon in the Launcher or search for Software Center in the Dash.
- When the Software Center opens, click the Installed button at the top.
- Find the application that you want to remove by using the search box or by looking through the list of installed applications.
- Select the application and click Remove.
- You may be asked to enter your password. After you have done that, the application will be removed.
Please note that some applications depend on other applications to work properly. If you try to remove an application that is needed by another application, both will be removed. You will be asked to confirm whether you want this to happen before the applications are removed.
