Exception in thread Thread-16 (most likely raised during interpreter shutdown):

While running setup wizard I encountered above error, and setup failed.

Seems related to threading, and the file calling the thread managements:

I edited the file /…/…/frappe-bench/env/lib/python2.7/site-packages/werkzeug/serving.py

**class ThreadedWSGIServer(ThreadingMixIn, BaseWSGIServer):**

** “”“A WSGI server that does threading.”""**
** multithread = True**
** daemon_threads = False**

and my setup was able to complete, is there a reason to setting daemon_threads = Truefrapp_setup_failed
