This article covers how to install and configure Homebrew on Ubuntu 20.04. In fact, Homebrew is one of the popular package managers for Mac OS X but can be installed on Linux as well to download and install various packages. 

Homebrew Cask extends Homebrew with support for quick installation of applications like Google Chrome, VLC, and more.

Differences between APT and Homebrew or Linuxbrew includes:

1. Both HomeBrew and APT’s main goal is the same that is the installation of various packages using the command line. However, on one hand, APT is the native and well-integrated manager of Debian-based systems including Ubuntu, HomerBrew is a third-party package manager that the user can install manually.

2. Difference in the command syntax, if a user is already familiar with the brew command line on macOS and new to Ubuntu then he or she can use it to install programs without learning new command hooks. However, if you are a user of Ubuntu or Debian, then for sure you don't need to install it.

3. Homebrew maintains a separate user-owned directory, thus no need to run it with sudo to install applications.

4. Where apt-get is generally designed to overwrite previous versions; in the brew, it compiles packages and saves them according to its version in subdirectories. This means we can have multiple versions of a package on the same machine at the same time, however, only one of them will get symlinked into your main Homebrew hierarchy.

5. APT cleanup or uninstall older packages automatically with the update, whereas, in Homebrew, a user needs to run the brew cleanup command.
