I don't know, I am not able to reproduce now, I have always error:

Debugger entered--Lisp error: (error "Empty checkout for helm-core")
  signal(error ("Empty checkout for helm-core"))
  error("Empty checkout for %s" helm-core)
  package-vc--unpack(#s(package-desc :name helm-core :version nil :summary "No

:main-file "helm-core.el"))
  (progn (package-vc-install '(helm-core :url
