Package: weasyprint Version: 51-1
When I invoke `weasyprint "https://www.google.com"; google.pdf' an error occurs, rather than the expected creation of *.pdf file. Here is a transcript: root@b4879d89318d:/home# weasyprint "https://www.google.com"; google.pdf Traceback (most recent call last): File "/usr/lib/python3.7/urllib/request.py", line 1319, in do_open encode_chunked=req.has_header('Transfer-encoding')) File "/usr/lib/python3.7/http/client.py", line 1252, in request self._send_request(method, url, body, headers, encode_chunked) File "/usr/lib/python3.7/http/client.py", line 1298, in _send_request self.endheaders(body, encode_chunked=encode_chunked) File "/usr/lib/python3.7/http/client.py", line 1247, in endheaders self._send_output(message_body, encode_chunked=encode_chunked) File "/usr/lib/python3.7/http/client.py", line 1026, in _send_output self.send(msg) File "/usr/lib/python3.7/http/client.py", line 966, in send self.connect() File "/usr/lib/python3.7/http/client.py", line 1422, in connect server_hostname=server_hostname) File "/usr/lib/python3.7/ssl.py", line 423, in wrap_socket session=session File "/usr/lib/python3.7/ssl.py", line 870, in _create self.do_handshake() File "/usr/lib/python3.7/ssl.py", line 1139, in do_handshake self._sslobj.do_handshake() ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1076) During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/weasyprint/urls.py", line 284, in fetch result = url_fetcher(url) File "/usr/lib/python3/dist-packages/weasyprint/urls.py", line 248, in default_url_fetcher timeout=timeout, context=ssl_context) File "/usr/lib/python3.7/urllib/request.py", line 222, in urlopen return opener.open(url, data, timeout) File "/usr/lib/python3.7/urllib/request.py", line 525, in open response = self._open(req, data) File "/usr/lib/python3.7/urllib/request.py", line 543, in _open '_open', req) File "/usr/lib/python3.7/urllib/request.py", line 503, in _call_chain result = func(*args) File "/usr/lib/python3.7/urllib/request.py", line 1362, in https_open context=self._context, check_hostname=self._check_hostname) File "/usr/lib/python3.7/urllib/request.py", line 1321, in do_open raise URLError(err) urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1076)> During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/bin/weasyprint", line 11, in <module> load_entry_point('WeasyPrint==51', 'console_scripts', 'weasyprint')() File "/usr/lib/python3/dist-packages/weasyprint/__main__.py", line 211, in main media_type=args.media_type) File "/usr/lib/python3/dist-packages/weasyprint/__init__.py", line 112, in __init__ with result as (source_type, source, base_url, protocol_encoding): File "/usr/lib/python3.7/contextlib.py", line 112, in __enter__ return next(self.gen) File "/usr/lib/python3/dist-packages/weasyprint/__init__.py", line 396, in _select_source with result as result: File "/usr/lib/python3.7/contextlib.py", line 112, in __enter__ return next(self.gen) File "/usr/lib/python3/dist-packages/weasyprint/__init__.py", line 406, in _select_source with fetch(url_fetcher, url) as result: File "/usr/lib/python3.7/contextlib.py", line 112, in __enter__ return next(self.gen) File "/usr/lib/python3/dist-packages/weasyprint/urls.py", line 286, in fetch raise URLFetchingError('%s: %s' % (type(exc).__name__, str(exc))) weasyprint.urls.URLFetchingError: URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1076)> I suggest that the "ca-certificates" should be added into "Depends". When the package ca-certificates is installed, weasyprint works well.
