The apt-get utility is a powerful command-line tool for managing packages in Debian and other Debian-based Linux distributions such as Ubuntu. In this guide, we will talk about basic apt-get commands and it's usage.

If you are installing a package with apt-get you need to use the following syntax.

Installing packages will also install all required dependencies for the program.

Updating package database.

You can update apt package database by using the following command. 

# sudo apt-get update

Update command will resynchronize the local database with the latest version. An update should always be performed before an install, upgrade or dist-upgrade.

Upgrading installed packages. 

Before we upgrade packages, make sure to update the local database with apt-get. After the database is updated, Use the following command to upgrade installed packages. 

# sudo apt-get upgrade

This will upgrade all installed packages on the server.

To remove a package, you can use the following command:

# sudo apt-get remove <package>

This will remove the package from your system, however, it does not remove any of the package configuration files. You can clear package configuration by using the following command:

# sudo apt-get purge
