Installing Unity Hub on Ubuntu 22.04

#gamedev #unity3d #ubuntu #linux

Introduction

There are two problems in the Unity Hub installation tutorial (Installing the Unity Hub on Linux):

Ubuntu 22.04 uses OpenSSL 3 while Unity Editors use OpenSSL 1.0 (Workaround for libssl issue on Ubuntu 22.04);
The second instruction uses the apt-key command, which is deprecated on Ubuntu 22.04 (apt-key Is Deprecated. How To Add OpenPGP Repository Signing Keys Without It).

Thus, I decided to provide this brief tutorial with the appropriate commands.

Tutorial

Downloading OpenSSL 1.0:

Download libssl1.0.0_1.0.2n-1ubuntu5.10_amd64.deb from http://archive.ubuntu.com/ubuntu/pool/main/o/openssl1.0/.

Installing OpenSSL 1.0:

sudo dpkg -i libssl1.0.0_1.0.2n-1ubuntu5.10_amd64.deb

Adding the Unity3D repository:

sudo sh -c 'echo "deb https://hub.unity3d.com/linux/repos/deb stable main" > /etc/apt/sources.list.d/unityhub.list'

Adding the public signing key:

wget -qO - https://hub.unity3d.com/linux/keys/public | sudo tee /etc/apt/trusted.gpg.d/unityhub.asc

Installing the Unity Hub:

sudo apt update
sudo apt install unityhub

Uninstalling the Unity Hub:

sudo apt remove unityhub

Super bro!
I would like to leave some comments here...if you're trying this tutorial after 27/04/2023 and maybe using something based on Ubuntu 22.04.2 LTS, you can find the right .deb here .

So, you need to run:
sudo dpkg -i libssl1.1_1.1.1-1ubuntu2.1~18.04.22_amd64.deb

Doing it, you can follow the next steps using this nice tutorial.

This worked for me, so I hope to help someone too. :)
