What did you do?

Git Cloned pkgsite and tried to use go get to get its dependencies

git clone git@github.com:golang/pkgsite.git ;
cd pkgsite ;
pwd ;
GOPROXY=proxy.golang.org go get golang.org/x/pkgsite ;
GOPROXY=goproxy.unx.sas.com go get golang.org/x/pkgsite

I ran these commands:

git clone git@github.com:golang/pkgsite.git ;
cd pkgsite ;
pwd ;
GOPROXY=proxy.golang.org go get golang.org/x/pkgsite ;
GOPROXY=goproxy.unx.sas.com go get golang.org/x/pkgsite

What did you expect to see?

I expected pkgsite dependencies to be download to the Go cache.
I tried the default GOPROXY and our company's internal GOPROXY. Both failed.
I have no issues downloading dependencies for other projects.
I can successfully run this 'go get' command from subdirs other than pkgsite as long as they have a go.mod

What did you see instead?

I know that it is not entirely necessary to do this normally, but the debugger that I use, GoLand insists on doing
a 'go get' on the main module whenever it debugs a project. This fails, so I cannot run the debugger.

There is no package to get at the module root.
