Vendor.json - How to determine obsolete packages?

I read about the vendor.json file here:

I checked the vendor.json file a bit and confirmed that these paths are broken (404):

Are all these paths in vendor.json obsolete?

Is there an easier way to check these than a manual check?

The git paths are not broken. GitHub simply doesn’t let you browser to subfolder in a repository. You have to go to something like to get to spf13/cobra/doc.

Keep packages in sync with govendor sync. That will download the vendored packages into hugo/vendor/*.

Thanks for the info.
