curl: (60) SSL certificate problem: unable to get local issuer certificate

Question

root@sclrdev:/home/sclr/certs/FreshCerts# curl --ftp-ssl --verbose ftp://{abc}/ -u trup:trup --cacert /etc/ssl/certs/ca-certificates.crt
* About to connect() to {abc         


        

Answer 1

I have solved this problem by adding one line code in cURL script:

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

Warning: This makes the request absolute insecure (see answer by @YSU)!
