    In rare cases a firewall might have blocked the download. Please look into the file and see if it contains text with further information.
-> IOException: The file 'C:\USERDATA\DEVEL\packages\Microsoft.Extensions.DependencyInjection\packageIcon.png' already exists.

It breaks on either Microsoft.Extensions.DependencyInjection or Microsoft.Extensions.DependencyInjection.Abstractions…

Also, paket restore --force breaks on various packages with

Paket failed with
-> Error during cleaning of C:\USERDATA\DEVEL\packages\Microsoft.AspNet.WebApi.Client
     - Access to the path 'C:\USERDATA\DEVEL\packages\Microsoft.AspNet.WebApi.Client\lib\net45' is denied.
-> UnauthorizedAccessException: Access to the path 'C:\USERDATA\DEVEL\packages\Microsoft.AspNet.WebApi.Client\lib\net45' is denied.

But this is a random race condition. Every time this appears its a different package.
