Steps to Install .NET 8 on Ubuntu 24.04

Follow the steps below to set up .NET 8.0 on your Ubuntu 24.04 machine. Let’s get started!

Prerequisites

Before we start, you need to have a few things ready:

  • An Ubuntu 24.04 system.
  • A user account with sudo (admin) permissions.
  • An internet connection.

Step 1: Update Your System

First, we need to make sure your system is up-to-date. Open your terminal and type these commands:

sudo apt update
sudo apt upgrade -y

Step 2: Install Required Dependencies

.NET required some extra software to work properly. You can install them by executing the following command:

sudo apt install -y apt-transport-https ca-certificates gnupg

Step 3: Add Microsoft Package Repository

Next, we will add the Microsoft package repository to your system. This will help us download and install .NET 8.0.

  1. Download the Microsoft signing key: 
    wget https://packages.microsoft.com/config/ubuntu/24.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
  2. Install the downloaded package: 
    sudo dpkg -i packages-microsoft-prod.deb
  3. Update the package list again: 
    sudo apt update

Step 4: Install .NET SDK

Now, we will install the .NET SDK, which has everything you need to build and run .NET applications.

  1. Install the .NET SDK: 
    sudo apt install -y dotnet-sdk-8.0

    To install previous version, You can simply replace dotnet-sdk-8.0 with that version like dotnet-sdk-6.0.

  2. Check the installation: 
    dotnet --version

    You should see the .NET 8.0 version number on your screen.

Step 5: Install .NET Runtime (Optional)

If you only need to run .NET applications, you can install just the runtime.

  1. Install the .NET Runtime: 
    sudo apt install -y dotnet-runtime-8.0
  2. Check the runtime installation: 
    dotnet --list-runtimes

    This command should list the installed runtimes, including .NET 8.0.

Step 6: Create a Simple .NET Application

Let’s create a simple .NET application to verify that everything is working correctly.

  1. Create a new console application: 
    dotnet new console -o dotnet-app
  2. Navigate to the application directory: 
    cd dotnet-app
  3. Run the application: 
    dotnet run

    You should see the output “Hello, World!” in your terminal.
