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

As mentioned above, users can run the commands below to install .NET 7 since it’s already included in Ubuntu’s repositories.

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

Since .NET 7 packages are not yet included in Ubuntu’s repositories, you must install the official Microsoft .NET repository.

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

Once the repository GPG key is installed, run the commands below to create a repository file for each version of Ubuntu.

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:
