This happens on Android where a SELinux policy prevents a plain user to bind() a pathname AF_UNIX socket (abstract and unnamed sockets are not constrained by this policy).The errors are:test_asyncio:======================================================================ERROR: test_start_unix_server_1 (test.test_asyncio.test_server.SelectorStartServerTests)----------------------------------------------------------------------Traceback (most recent call last):File "/data/local/tmp/python/lib/python3.8/test/test_asyncio/test_server.py", line 105, in test_start_unix_server_1  srv = self.loop.run_until_complete(asyncio.start_unix_server(File "/data/local/tmp/python/lib/python3.8/asyncio/base_events.py", line 589, in run_until_complete  return future.result()File "/data/local/tmp/python/lib/python3.8/asyncio/streams.py", line 115, in start_unix_server  return await loop.create_unix_server(factory, path, **kwds)File "/data/local/tmp/python/lib/python3.8/asyncio/unix_events.py", line 285, in create_unix_server  sock.bind(path)PermissionError: [Errno 13] Permission deniedtest_socket:======================================================================ERROR: test_socket_fileno (test.test_socket.GeneralModuleTests)----------------------------------------------------------------------Traceback (most recent call last):File "/data/local/tmp/python/lib/python3.8/test/test_socket.py", line 1780, in test_socket_fileno  s.bind(os.path.join(tmpdir, 'socket'))PermissionError: [Errno 13] Permission deniedtest_stat:======================================================================ERROR: test_socket (test.test_stat.TestFilemodeCStat)----------------------------------------------------------------------Traceback (most recent call last):File "/data/local/tmp/python/lib/python3.8/test/test_stat.py", line 198, in test_socket  s.bind(TESTFN)PermissionError: [Errno 13] Permission denied======================================================================ERROR: test_socket (test.test_stat.TestFilemodePyStat)----------------------------------------------------------------------Traceback (most recent call last):File "/data/local/tmp/python/lib/python3.8/test/test_stat.py", line 198, in test_socket  s.bind(TESTFN)PermissionError: [Errno 13] Permission denied
