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

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

To install the 💿 .NET Core SDK Ubuntu setup requires adding Microsoft’s software repository to your system so you can download and install the development tools. You will register the Microsoft package signing key, add the software feed to your package manager, and then use the apt command-line tool to download the ⬇️ software package.

Below is how to install it 💿 on Ubuntu Linux.

This package allows you to install the 💿 .NET SDK securely via HTTPS.

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 tells your package manager where to download official Microsoft software packages. You use the wget command to download the Microsoft configuration package and install it using dpkg so your system trusts the official software feed.

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

The lines above create a /etc/apt/sources.list.d/microsoft-prod. Next, list the repository file on your Ubuntu Linux system with appropriate config settings.

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

Installing the .NET Core SDK on Ubuntu Linux requires updating your local package list and running the installation command for your chosen version. You use the sudo apt update command followed by sudo apt install dotnet-sdk-6.0 to set up the development environment on your computer.

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 via Snap gives you an alternative method that packages the software with all its required dependencies. You use the snap command-line tool to install the .NET SDK directly without needing to configure external software repositories or signing keys.

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!
