How to Install .NET 7 on Ubuntu Linux

How to install .NET 7 on Ubuntu Linux

As described above, Microsoft announced the release of .NET 7 with enhanced Linux and native ARM64 support.

Below is how to install it 💿 on Ubuntu Linux.

Install .NET 6

To install .NET 6 on Ubuntu, you can use the built-in package manager to get the software quickly. Running two quick commands in your terminal adds the required development tools and runtime files to your system without needing any extra download sources.

To install .NET 6, run the commands below.

sudo apt update
sudo apt install dotnet6

The commands above will install all the SDK, Runtime, and ASP.NET packages.

You can install each of the features separately using the commands below.

sudo apt install dotnet-sdk-6.0
sudo apt install dotnet-runtime-6.O
sudo apt install aspnetcore-runtime-6.0

Install .NET 7

The .NET 7 Ubuntu installation requires setting up Microsoft's official software repository first because the package is not available in the default Ubuntu app lists. You need to download the security key and configure your system to trust the official Microsoft download source before running the install command.

First, run the commands below to add the Microsoft repository's GPG key.

sudo apt install curl
curl https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor | sudo dd of=/usr/share/keyrings/microsoft.gpg

For version 22.04:

echo 'deb [arch=amd64 signed-by=/usr/share/keyrings/microsoft.gpg] https://packages.microsoft.com/ubuntu/22.04/prod jammy main' | sudo tee /etc/apt/sources.list.d/microsoft.list >/dev/null

For version 20.04:

echo 'deb [arch=amd64 signed-by=/usr/share/keyrings/microsoft.gpg] https://packages.microsoft.com/ubuntu/20.04/prod focal main' | sudo tee /etc/apt/sources.list.d/microsoft.list >/dev/null

For version 18.04:

echo 'deb [arch=amd64 signed-by=/usr/share/keyrings/microsoft.gpg] https://packages.microsoft.com/ubuntu/18.04/prod bionic main' | sudo tee /etc/apt/sources.list.d/microsoft.list >/dev/null

After adding the repository's key and file, run the commands below to install .NET 7.

sudo apt update
sudo apt install dotnet-sdk-7.0
sudo apt install dotnet-runtime-7.0 
sudo apt install aspnetcore-runtime-7.0

To see information about .NET, run the commands below.

dotnet --info

That should output similar lines as below:
