Solution:
I had the same issue. I found this solution https://github.com/Automattic/developer/commit/69423f8a479a6d343e146a8b20d77b7f9ac66835.
You just to add $context = false, $allow_relaxed_file_ownership = false in your class-empty-upgrader-skin.php file which you can locate in plugins/developer/include folder.
