Attempting to add a nuget package to a new console application results in the error Value cannot be null. (Parameter 'path1').

Expected behaviour: Running dotnet add package Microsoft.Extensions.Configuration.Json works without any errors.

Actual behaviour: error: Value cannot be null. (Parameter 'path1')

Steps to reproduce:

1. dotnet new console -o test -n Test
2. cd test
3. dotnet add package Microsoft.Extensions.Configuration.Json

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

From the detailed error message you provided:

error: NU3028: Package 'Microsoft.Extensions.Configuration.Json 5.0.0' from source 'https://api.nuget.org/v3/index.json': The author primary signature's timestamp found a chain building issue: UntrustedRoot: self signed certificate in certificate chain

This seems to be the real cause error, there was something going wrong with the package's certs. I'm not able to repro this issue, is it still happening for you?

I just ran into this same issue (I think).

I executed "dotnet add package Microsoft.AspNetCore.Mvc" and ended with a couple of errors:

Edit: after reviewing the file, there's actually a long chain of info-info-info-error messages, similar to the above.

Before finding this issue, I tried blowing away my package cache, so the output after running my command is very long. I've thrown the entire output, from command to end, into dotnet_error.txt

FWIW I'm on Gentoo Linux, running version 5.0.200.

Clearing up nuget cache helped me to negotiate with expired certificate.
