Errors of restoring dependencies

There is a issue during restoring dependencies: excel.activities, mail.activities, system.activites, UIAutomation.activities

I have tried uninstalling and reinstalling the package, but doesn’t work
I have tried to install several applicable previous versions of the package, but doesn’t work

Log of error:

The feed ‘ []’ lists package ‘Microsoft.Identity.Client.4.14.0’ but multiple attempts to download the nupkg have failed. The feed is either invalid or required packages were removed while the current operation was in progress. Verify the package exists on the feed and try again.


This error still exists, can someone help on this? Thanks a lot.
