Introduction

You could run into different package management instructions when working with Linux-based operating systems like Ubuntu or Debian. “apt-get,” one of the frequently used commands, enables users to install, manage, and update software packages from repositories. However, occasionally you could see a notice that says “apt-get command not found.” You can follow the instructions in this article to fix the problem and get the crucial “apt-get” command working again.

Understanding the apt-get command

Let’s take a moment to grasp what this command performs before we get started on correcting the “apt-get command not found” error. In Linux distributions based on Debian, “apt-get” is a potent package management tool. The Advanced Packaging Tool (APT) can be used by users to install, update, and uninstall software packages from the system.

Common causes of the “apt-get command not found” error

There are several reasons why you might encounter the “apt-get command not found” error. Understanding these causes will help us troubleshoot the issue effectively. Some common reasons include:

Outdated package manager

The first and most straightforward explanation could be that your package manager is outdated or not properly configured. An outdated APT can lead to the “apt-get command not found” error. Let’s explore how to check and update the package manager.

Missing or corrupted files

Another possibility is that essential files related to the APT system or the “apt-get” command might be missing or corrupted. This can occur due to various reasons, such as software conflicts or improper system shutdowns.

Checking the system for existing package managers

Before attempting any fixes, it’s essential to check if any other package managers are installed on your system. Some Linux distributions might use different package managers by default. To check for existing package managers, follow these steps:

1. Open the terminal on your system.
2. Type the following command and press Enter:

dpkg --get-selections | grep -v deinstall

Installing apt-get on Ubuntu and Debian-based systems

If you have confirmed that your system lacks the “apt-get” command, it’s time to install it. Follow these steps to install “apt-get” on Ubuntu and Debian-based systems:

1. Open the terminal.
2. Type the following command and press Enter:
