I dumped into this issue after moving a client Drupal 7 website from their Hosting Provider to my Superfast Web Servers powered by NGINX and Varnish Caching.
warning: fileowner(): stat failed for temporary://update_zgp3da in update_manager_local_transfers
Workaround:
1. Login to admin backend
2. Go to Configuration > Media > File System
3. Check the values entered in:
◦Public file system path
◦Temporary directory
4. Double-check those paths, directories, or folders are existing in your system folders (in most cases, the “tmp” folder is missing, therefore creating a folder in your Drupal site root level will fix the issue)
5. Try installing or updating your Drupal again after folder paths are created
NB:
