Drupal 8 curl 60 error

Question

I can't update drupal 8 modules on local because I have the error message

"Failed to fetch file due to error "cURL error 60: SSL certificate problem: self signed certificate in certificate chain (see http://curl.haxx.se/libcurl/c/libcurl-errors.html )"

I use Wamp 3 and php 7.0.10. I have tried the solution indicates for this problem :

• Download cacert.pem on curl site and save in "c:\\windows"
• Set curl.cainfo = "c:\\Windows\\cacert.pem" and openssl.cafile= "c:\\Windows\\cacert.pem" on C:\\wamp64\\bin\\php\\php7.0.10\\php.ini and C:\\wamp64\\bin\\apache\\apache2.4.23\\bin\\php.ini (.simlink)
• Restart all services

The problem is still there.

I have tested many advices on forum : - Put the cacert.pem in wamp directories and changes paths in 2 php.ini - Test with other php versions ...

For information Curl is well enabled. I've checked it with phpinfo().

Answer 1

This error message means the distant server did not trust your certificate

see some links about that :
