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

Had that problem and it was not solved with newer version. /etc/certs had the root cert, the browser said everything is fine. After some testing I got from ssllabs.com the warning, that my chain was not complete (Indeed it was the chain for the old certificate and not the new one). After correcting the cert chain everything was fine, even with curl.
