Hi, I had a python code based on SPARQL-Wrapper 1.8.2 that queries an "https" SPARQL end-point. It worked fine until now.
But since the SSL certificate was updated on that SPARQL end-point last week, I now do get an error: "urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:645)" There seems to be an issue with the CA as a curl was also failing and firefox gave a "SEC_ERROR_UNKNOWN_ISSUER*"*. My next step was to add the public key of that certificate manually. I did add the public key to my ubuntu system (new .crt file, update-ca-certificates command), and the curl works now fine. The public certificate was added to "/etc/ssl/certs/ca-certificates.crt" However, I did not find a way to get my python script working again, the problem is still there. I am struggling with this since quiet a few hours, hence asking for your help. I did try a few things, like: - writing simple code to access the end-point -> that code fails with the same error as SPARQL-Wrapper import requests url = 'https://lindas-data.ch:8443/alod/query' session = requests.Session() response = session.get(url) - making some variables (export) to that .crt file (REQUESTS_CA_BUNDLE, SSL_CERT_FILE, SSL_CERT_DIR) no change - installing "certifi", and add my public certificate to the file given by certifi.where(): '/home/fabian/.local/lib/python3.5/site-packages/certifi/cacert.pem' no change Would you have any pointer ?
