Unable to locate package dotnet-sdk-8.0

I've moved of my applications to .Net 8 and I use ubuntu 22.04.3 LTS VPS to host my web applications.

I'm trying to install .net 8 on the VPS but I can't

I've tried the Scripted install by microsoft it didn't work

I've tried the Debian install by microsoft it didn't work

When I run the basic command for ubuntu

sudo apt-get update && \  sudo apt-get install -y dotnet-sdk-8.0

I get the following errer even after updating & Upgrading ubuntu
