How to fix 'The repository 'https://packages.microsoft.com/repos/microsoft-ubuntu-22.04-prod jammy Release' does not have a Release file.'

Question

I am trying to publish a .NET 5.0 Web API to an Ubuntu Server with a 22.04 version, and when I want to install the .NET 7.0 since the 5.0 is no longer supported running the below command

sudo apt-get update && \   sudo apt-get install -y dotnet-sdk-7.0

I get this error message

Hi @Bashar Muhanna

And when I visit the repo link is show 404 error. https://packages.microsoft.com/repos/microsoft-ubuntu-22.04-prod

The issue occurs when the Microsoft repository is not configured correctly for your Ubuntu release. As you said, when visit the above link, it will show the 404 error. The correct url should be as below:

https://packages.microsoft.com/ubuntu/22.04/prod/

More detail information, see Linux Software Repository for Microsoft Products and Install the .NET SDK or the .NET Runtime on Ubuntu.
