Master Ubuntu Apt and Become an Apt Guru

While it is easy to install and manage many applications from the Ubuntu Software Center, it is often convenient to be able to manage installation and other operations from the command prompt. In Ubuntu, management and installation of applications from the command line is handled by APT (Advanced Package Tool).

Mastering this will allow you to have better control over the process of installing applications on your machines. As you become more familiar with Ubuntu APT, you’ll even be able to manage your installed apps faster through the command line than with the included GUI Software Center.

Note: unless you are logged in with the root account on your system, you will need to use sudo in front of the commands below.

Installation of the application

There are several different commands associated with installing applications with APT.

Install a new package

To install a new package, use the command below:

Ubuntu Apt Guru Installer 4

Install multiple packages with a single line of code

Instead of installing the packages one by one, they can also be installed using the command below:

Ubuntu Apt Guru Install multipleUbuntu Apt Guru Install multiple

Package deletion

There are a few options for removing packages in APT. Deleting packages is more nuanced than simply deleting files from a folder, and the commands available to support deleting packages support it.

Remove a package while leaving the configuration files intact

If you want to remove a package from your computer while leaving the configuration files intact, you can use the command below. This method is useful for packages that you can reinstall later.

Remove package with configuration files

If you want to remove all configuration files associated with a package, use the command below. This command is useful for packages that you do not plan to reinstall and would like to see completely removed from your system.

Remove one package and install another in one go

It is actually quite common to remove one package because another is more appropriate. Whatever the reason, you can remove a package and install a package with one command. If you want to do this, enter the following:

In this case, you will remove package1 and install package2.

You can combine this with removing packages, so that all unnecessary packages are removed when you uninstall a package.

Maintain your Ubuntu system with APT

Just like with a physical object, you will need to perform maintenance on your Ubuntu system from time to time.

Update system packages

You should update your system packages regularly to keep your system running in optimal condition. The command below resynchronizes the package index files with their sources.

Localization of packages with keywords

To search for a package containing a particular keyword, you can use the command:
