Server on not working after installation (failed with HaltServer)

[fspinar]

Hi all,

I am trying to run the server on comment after installation, as instructed in the documentation (https://psiturk.readthedocs.io/en/latest/quickstart.html#step-1-install-psiturk) Yet I get the following error :

Traceback (most recent call last): File "src/gevent/greenlet.py", line 906, in gevent._gevent_cgreenlet.Greenlet.run File "/home/faspinar/.local/lib/python3.8/site-packages/gunicorn/arbiter.py", line 242, in handle_chld self.reap_workers() File "/home/faspinar/.local/lib/python3.8/site-packages/gunicorn/arbiter.py", line 525, in reap_workers raise HaltServer(reason, self.WORKER_BOOT_ERROR) gunicorn.errors.HaltServer: <HaltServer 'Worker failed to boot.' 3> 2021-06-25T09:31:27Z <Greenlet at 0x7f2fa5e626a0: <bound method Arbiter.handle_chld of <gunicorn.arbiter.Arbiter object at 0x7f2fa60fc0d0>>(17, None)> failed with HaltServer

Any idea how to solve this ? I realized other people also experienced this and tried some suggestions I saw on the Web, but none worked so far. I installed psiturk 3.2.0and have python 2.7 3.8 3.9 . I am working on WSL2 , but don't know whether this effects anything in anyway.

Thanks all.

Check your server.log file for the error messages.

Ok I checked and I got : self._sock = self._gevent_sock_class(family, type, proto, fileno) OSError: [Errno 92] Protocol not available

Any suggestion for solving this ?

Thank you.

That's the only entry in your server.log file?

I tried many times and in the log file the same error is replicated... To be complete the full error is :

Traceback (most recent call last): File "/home/faspinar/.local/lib/python3.8/site-packages/gunicorn/arbiter.py", line 583, in spawn_worker worker.init_process() File "/home/faspinar/.local/lib/python3.8/site-packages/gunicorn/workers/ggevent.py", line 160, in init_process self.patch() File "/home/faspinar/.local/lib/python3.8/site-packages/gunicorn/workers/ggevent.py", line 61, in patch sockets.append(socket.socket(s.FAMILY, socket.SOCK_STREAM, File "/home/faspinar/.local/lib/python3.8/site-packages/gevent/_socket3.py", line 133, in init self._sock = self._gevent_sock_class(family, type, proto, fileno) OSError: [Errno 92] Protocol not available

Is this full version kind of better ?

Thanks

Hmm try from a virtual environment, to rule out a missing package install. I run psiturk from wsl 2 ubuntu 18 without incident.

It is interesting but the error is simply gone when I switch to Ubuntu 18.04 (from 20.04) on WLS2. Thanks !
