Cannot vendor k8s httplog

[FrenchBen]

Sample code:

package main

import (
	"io/ioutil"
	"os"

	_ "k8s.io/kubernetes/pkg/client/metrics/prometheus" // for client metric registration
	"k8s.io/kubernetes/pkg/kubectl/cmd"
	cmdutil "k8s.io/kubernetes/pkg/kubectl/cmd/util"
	_ "k8s.io/kubernetes/pkg/version/prometheus" // for version metric registration

	"github.com/spf13/cobra/doc"
)

func main() {
	kubectl := cmd.NewKubectlCommand(cmdutil.NewFactory(nil), os.Stdin, ioutil.Discard, ioutil.Discard)
	doc.GenMarkdownTree(kubectl, "./")
}

End of trash -u output:

Try to remove trash cache: rm -fr ~/.trash-cache.

[FrenchBen]

That worked - Can you explain why the cache was at fault here?
Perhaps there should be a purge cmd for the cache?

I'm getting the same error message for other packages, and removing the cache doesn't help. This happens on a fresh machine without ever having had trash run before but from a repo that has been in development for some time.
