Debian 7上的卷曲不'；t似乎没有使用/etc/ssl/certs/ca-certificates.crt

当我运行以下命令时：

# curl https://undisclosedwebsite.nl

我得到以下错误：

curl: (60) SSL certificate problem: unable to get local issuer certificate
More details here: http://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.

使用

openssl s_客户端进行调试后-连接https://undisclosedwebsite.nl

我发现以下带有cURL的命令确实有效：

curl https://undisclosedwebsite.nl --cacert /etc/ssl/certs/ca-certificates.crt

cURL不应该使用这个文件吗
