SSL Error while building Python from sources

I'm trying to install on my Jetson Nano board (Ubuntu) a specific Python version from sources and get an error which I don't know how to fix this. I do:

• wget https://www.python.org/ftp/python/3.5.7/Python-3.5.7.tgz
• tar
• zxvf Python-3.5.7.tgz cd Python-3.5.7
• ./configure --enable-shared --enable-optimizations
• make

And after some time I recieve:

0:34:25 load avg: 1.10 [189/391] test_logging --- Logging error --- Got an error: [SSL: SSLV3_ALERT_CERTIFICATE_EXPIRED] sslv3 alert certificate expired (_ssl.c:728) Traceback (most recent call last): File "/home/dlinano/Documents/Python-3.5.7/Lib/logging/handlers.py", line 1184, in emit h.endheaders() File "/home/dlinano/Documents/Python-3.5.7/Lib/http/client.py", line 1103, in endheaders self._send_output(message_body) File "/home/dlinano/Documents/Python-3.5.7/Lib/http/client.py", line 934, in _send_output self.send(msg) File "/home/dlinano/Documents/Python-3.5.7/Lib/http/client.py", line 877, in send self.connect() File "/home/dlinano/Documents/Python-3.5.7/Lib/http/client.py", line 1261, in connect server_hostname=server_hostname) File "/home/dlinano/Documents/Python-3.5.7/Lib/ssl.py", line 385, in wrap_socket _context=self) File "/home/dlinano/Documents/Python-3.5.7/Lib/ssl.py", line 760, in init self.do_handshake() File "/home/dlinano/Documents/Python-3.5.7/Lib/ssl.py", line 996, in do_handshake self._sslobj.do_handshake() File "/home/dlinano/Documents/Python-3.5.7/Lib/ssl.py", line 641, in do_handshake self._sslobj.do_handshake() ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:728) Call stack: File "/home/dlinano/Documents/Python-3.5.7/Lib/runpy.py", line 193, in _run_module_as_main "main", mod_spec) File "/home/dlinano/Documents/Python-3.5.7/Lib/runpy.py", line 85, in _run_code exec(code, run_globals) File "/home/dlinano/Documents/Python-3.5.7/Lib/test/regrtest.py", line 1833, in main_in_temp_cwd() File "/home/dlinano/Documents/Python-3.5.7/Lib/test/regrtest.py", line 1808, in main_in_temp_cwd main() File "/home/dlinano/Documents/Python-3.5.7/Lib/test/regrtest.py", line 873, in main runtest_accumulate() File "/home/dlinano/Documents/Python-3.5.7/Lib/test/regrtest.py", line 863, in runtest_accumulate match_tests=ns.match_tests, pgo=ns.pgo) File "/home/dlinano/Documents/Python-3.5.7/Lib/test/regrtest.py", line 1108, in runtest pgo=pgo) File "/home/dlinano/Documents/Python-3.5.7/Lib/test/regrtest.py", line 1403, in runtest_inner test_runner() File "/home/dlinano/Documents/Python-3.5.7/Lib/test/support/init.py", line 1565, in inner return func(*args, **kwds) File "/home/dlinano/Documents/Python-3.5.7/Lib/test/test_logging.py", line 4298, in test_main support.run_unittest(*tests) File "/home/dlinano/Documents/Python-3.5.7/Lib/test/support/init.py", line 1901, in run_unittest _run_suite(suite) File "/home/dlinano/Documents/Python-3.5.7/Lib/test/support/init.py", line 1857, in _run_suite result = runner.run(suite) File "/home/dlinano/Documents/Python-3.5.7/Lib/test/support/init.py", line 1740, in run test(result) File "/home/dlinano/Documents/Python-3.5.7/Lib/unittest/suite.py", line 84, in call return self.run(*args, **kwds) File "/home/dlinano/Documents/Python-3.5.7/Lib/unittest/suite.py", line 122, in run test(result) File "/home/dlinano/Documents/Python-3.5.7/Lib/unittest/suite.py", line 84, in call return self.run(*args, **kwds) File "/home/dlinano/Documents/Python-3.5.7/Lib/unittest/suite.py", line 122, in run test(result) File "/home/dlinano/Documents/Python-3.5.7/Lib/unittest/case.py", line 653, in call return self.run(*args, **kwds) File "/home/dlinano/Documents/Python-3.5.7/Lib/unittest/case.py", line 605, in run testMethod() File "/home/dlinano/Documents/Python-3.5.7/Lib/test/test_logging.py", line 1710, in test_output logger.error(msg) Message: 'spдm' Arguments: ()

I've never seen this before and there's nothing similar over the internet
