Installing the Unity Hub on Linux: A Step-by-Step Guide

To install the Unity Hub on a Debian or Ubuntu Linux distribution, you need to follow a series of steps that involve adding the Unity Hub Debian repository and installing the required package. In this section, we will break down the process into manageable steps, explaining each command and its purpose.

Step 1: Adding the Public Signing Key

The first step is to add the public signing key to verify the integrity of the packages. This key ensures that the packages you download are authentic and have not been tampered with.

Open a terminal and run the following command:

wget -qO - https://hub.unity3d.com/linux/keys/public | gpg --dearmor | sudo tee /usr/share/keyrings/Unity_Technologies_ApS.gpg > /dev/null

Let’s break down this command:

• The > /dev/null option redirects any output to /dev/null, effectively suppressing it.
• The wget command is used to download the public signing key from the Unity website.
• The -qO – option tells wget to download the key quietly and output it to the standard output.
• The gpg –dearmor command decrypts the downloaded key and removes any ASCII armor (a format used to encode binary data as text).
• The sudo tee command writes the decrypted key to the /usr/share/keyrings/Unity_Technologies_ApS.gpg file.

Step 2: Adding the Unity Hub Repository

Next, you need to add the Unity Hub repository to your system. This repository contains the packages required for installing the Unity Hub.

Run the following command:

sudo sh -c 'echo "deb [signed-by=/usr/share/keyrings/Unity_Technologies_ApS.gpg] https://hub.unity3d.com/linux/repos/deb stable main" > /etc/apt/sources.list.d/unityhub.list'

  Here’s what this command does:

• The > /etc/apt/sources.list.d/unityhub.list option writes the repository definition to a file called unityhub.list in the /etc/apt/sources.list.d directory.
• The sudo sh -c option runs the command as the superuser and captures the output.
• The echo command outputs the string that defines the repository.
•  The deb [signed-by=/usr/share/keyrings/Unity_Technologies_ApS.gpg] option specifies that the repository is signed by the key you added in Step 1.
• The https://hub.unity3d.com/linux/repos/deb stable main is the URL of the Unity Hub repository.

Step 3: Updating the Package Cache and Installing the Unity Hub

Finally, you need to update your package cache and install the Unity Hub package.

Run the following commands:

sudo apt-get install unityhub

To launch the Unity Hub, you can use the following command:

unityhub

This command will start the Unity Hub, and you can begin creating and managing your Unity projects.
