Unable to install or update any package through Package manager console

Vote:
 

I am unable to update any existing Episerver CMS packages or install new packages like EPiServer.Marketing.Testing through Packages manager console. I am currently using visual studio 2017 and tried restarting Visual studio and also cleared nuget cache. Please have a look at below details of error. Package source is set to 'All' and default project to current project.

PM> Install-Package EPiServer.Marketing.Testing -ProjectName EPIAlloyDemo
Install-Package : Unable to find package 'EPiServer.Marketing.Testing'

When trying to update CMS to highest minor:

Update-Package EPiServer.CMS -ProjectName EPIAlloyDemo -ToHighestMinor

Please let me know if i need to make any changes before running these commands or if i am doing anything incorrectly.

Thank you.

Hi Ravichandra, 

Please check the Episerver package source does exist in your VS17 or not, if not then go to Tools - Options - NuGet Package Manager - add (+).

And then restart your visual studio and hit the command.

Thanks,

I have added EPI server package source later and it worked.
