curl: (60) SSL certificate problem: unable to get local issuer certificate
More details here: https://curl.haxx.se/docs/sslcerts.html
curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.
This issue is caused by one of the following reasons:
(Please note that a Linux OS can only be protected via IPSec tunnel or Proxy Forwarding access methods).
Add the WSS root certificate to the your operating system store:
Create a directory for extra CA certificates in
sudo mkdir /usr/share/ca-certificates/extra
CertEmulationCA.crt file to this directory:
sudo cp CertEmulationCA.crt /usr/share/ca-certificates/extra/CertEmulationCA.crt
Update ca-certificates configuration to include the recently imported certificate.
sudo dpkg-reconfigure ca-certificates
Alternatively, you can instruct cURL to use the certificate when running the command:
curl --cacert c:\temp\CertEmulationCA.crt https://www.securesite.com/
