How to Install .NET Core (dotnet) SDK on Ubuntu Linux

How to install dotnet (.NET) SDK on Ubuntu Linux

Installing the .NET Core SDK on Ubuntu Linux means getting your system ready to download software safely. You’ll set up Ubuntu to trust Microsoft’s official software sources and add the .NET repository. This guide shows you the exact steps to get the SDK installed and running.

Below is how to install it on Ubuntu Linux.

To do that, install the apt-transport-HTTP package using the command below.

sudo apt update
sudo apt install apt-transport-https

Add .NET Repository

Adding the .NET repository to your Ubuntu system is how you tell it where to find official .NET software. You’ll use a specific command to download and install this list of software from Microsoft. This step is important to make sure you get the right and latest version of the .NET Core SDK.

wget https://packages.microsoft.com/config/ubuntu/20.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb

If you’re using a different version of Ubuntu Linux, replace the highlighted version number in the commands above.

Install .NET Core SDK on Ubuntu Linux

After adding the Microsoft repository, installing the .NET Core SDK on Ubuntu Linux is straightforward. You just need to run two commands: first, to update your system’s software list, and second, to install the SDK itself. This process makes sure your system has the tools needed to run .NET apps.

sudo apt update
sudo apt install dotnet-sdk-6.0

After installing, you should get a success message similar to the one below:

Welcome to .NET!
---------------------
Learn more about .NET: https://aka.ms/dotnet-docs
Use 'dotnet --help' to see available commands or visit: https://aka.ms/dotnet-cli-docs

Once .NET SDK is installed, you can verify by running the commands below.

dotnet --list-sdks

The command above will display the version of .NET installed.

Output:
6.0.300 [/usr/share/dotnet/sdk]

Also, verify that the .NET runtime is functioning.

dotnet --list-runtimes

That should display similar lines as shown below:

Output:
Microsoft.AspNetCore.App 6.0.5 [/usr/share/dotnet/shared/Microsoft.AspNetCore.App]
Microsoft.NETCore.App 6.0.5 [/usr/share/dotnet/shared/Microsoft.NETCore.App]

The commands below can also be used to install .NET Framework independently.

sudo apt install dotnet-runtime-6.0 

How to install .NET Core SDK on Ubuntu via Snap

Installing the .NET Core SDK on Ubuntu using Snap offers a different way than the usual repository method. Snaps bundle applications with everything they need, making them easy to install and manage. This approach simplifies getting the .NET SDK onto your Ubuntu system without needing to add extra software sources.

Snaps are containerized software packages that are simple to create and install.

Snap applications are packaged with all their dependencies to run on all popular Linux distributions from a single build, allowing them to update automatically and roll back gracefully.

To install .NET via snap, run the commands below:

sudo apt install snap 
sudo snap install dotnet-sdk --classic

After installing, you can begin building great applications.

That should do it!
