What is a Linux Package?

A Linux package is an archive used for installing, maintaining and removing software on a Linux-based device. You can look at packages (and their managers) as being the equivalent of executable installers on a Windows computer. In Linux, a repository administers sets of packages, which include all the files necessary to manage an application's existence on a device. It also includes a list of dependencies that detail what software (and its versions) must be installed on the device in order for the application to function correctly.

You need packages in Linux because not every Linux device has been configured in the same way. So, an application that will run on one device may not run on another.

Based on the distribution of Linux that you are using, there are different package managers. For example, if you are using a Debian-based distribution, such as Ubuntu, Elementary OS and Linux Mint, you can use apt. If you are using a Red Hat-based distribution, you can use rpm.
