Thank you for raising this issue. Unfortunately you haven't provided any information on how someone else can reproduce the problem you are experiencing. Can you please include a way that someone else can reproduce the problem you are seeing.

IMPORTANT: Please do not include screenshots of text, just copy and paste the text directly

My login user to my computer has no permission to create any file under the C:\Users directory.
I guess to reproduce this issue, login without the admin user could be the way.

It looks like you have a copy of k8s.io/kubernetes checked out in $HOME/go/src/k8s.io/kubernetes. Is that correct?
Which directory are you in? is it $HOME/go/src/k8s.io/kubernetes?

If you can provide a set of commands that gets a windows machine with Go installed to the point of the command that failed; ie, git clone (or however you did it), cd $directory, go mod vendor. That would be of great assistance.

C:\Users shouldn't be your project's directory.

go/src/cmd/go/internal/modcmd/vendor.go

Line 302 in 666315b

pkg = filepath.Dir(pkg)

This should be:

pkg = path.Dir(pkg)

Since pkg is a paths separated with slash (not backslash). I'll send CL.

So you mean this is a bug and will be fixed in a future release?

which shell / environment (WSL?) are you using?

[breeze7086]

which shell / environment (WSL?) are you using?

I'm using MobaXterm under the Windows system, I'm sorry to say I have no idea what kind of shell does it use.
Maybe this could help?

I can reproduce this failure mode locally using the stock cmd.exe shell in a current clone of the https://github.com/kubernetes/kubernetes repo:
