NU1101Unable to find package Pluralsight.DDD.Deps. No packages exist with this id in source(s): Microsoft Visual Studio Offline Packages, nuget.org

I am trying to learn a course in pluralsight https://app.pluralsight.com/library/courses/fundamentals-domain-driven-design/table-of-contents and I have a demo application for the course available at https://github.com/ardalis/pluralsight-ddd-fundamentals.

But, during the build one of the custom public nuget package restore fails:

Severity    Code    Description Project File    Line    Suppression StateError   NU1101  Unable to find package Pluralsight.DDD.Deps. No packages exist with this id in source(s): Microsoft Visual Studio Offline Packages, nuget.org   FrontDesk.Blazor.Host   C:\Users\ArunPaul\source\repos\DDD\pluralsight-ddd-fundamentals\FrontDesk\src\FrontDesk.Blazor.Host\FrontDesk.Blazor.Host.csproj    1   

When i checked the nuget repository, it doesn't exists, but the closest package available isPluralsightDdd.SharedKernel.I tried for building the application with the PluralsightDdd.SharedKernel package but it never builds.

Can someone suggest a solution?
