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.

我本想评论Yuvik的回答，但我缺乏足够的声誉点。

当您将.crt文件导入到/usr/share/local/ca-certificates时，需要使用正确的格式。其中一些已经在前面提到过，但是还没有人提到只需要一个新的行字符，也没有人收集过清单，所以我想在这里提供一个清单。

The certificate needs to end in .crt. From Ubuntu's man page: Certificates must have a .crt extension in order to be included by update-ca-certificates Certificate files in /usr/local/share/ca-certificates can only contain one certificate Certificate files must end in a newline. update-ca-certificates will appear to work if each row contains, for example, a carriage return + a newline (as is standard in Windows), but once the certificate is appended to /etc/ssl/ca-certificates.crt, it still will not work. This specific requirement bit me as we're loading certificates from an external source.

仅仅更新证书列表可能就足够了

sudo update-ca-certificates -f

update-ca-certificates是一个更新/etc/ssl/certs目录以保存SSL证书并生成ca-certificates的程序。Crt，一个连接的证书单文件列表。

我们最近遇到了这个错误。事实证明，这与根证书没有正确安装在CA存储目录有关。我使用了一个curl命令，其中我直接指定了CA目录。Curl——cacert /etc/test/server。—capath /etc/test…此命令每次都失败，curl: (60) SSL证书问题:无法获得本地颁发者证书。

在使用strace curl…根据openssl哈希命名约定，curl正在查找名称为60ff2731.0的根证书文件。所以我发现这个命令可以有效地导入根证书:

Ln -s rootcert。pem的openssl x509散列-noout——rootcert.pem ' 0

哪个会创建软链接

60f2731.0 ->找到脚

卷曲，在被子下读取服务器。pem，确定根证书文件的名称(rootcert.pem)，将其转换为其哈希名称，然后进行操作系统文件查找，但无法找到它。

因此，结论是，当curl错误很模糊时，在运行curl时使用strace(这是一个巨大的帮助)，然后确保使用openssl命名约定正确安装根证书。

有这个问题，但新版本没有解决。/etc/certs有根证书，浏览器说一切正常。经过一些测试后，我从ssllabs.com得到警告，我的链是不完整的(实际上这是旧证书链，而不是新证书链)。在纠正了证书链之后，一切都很好，即使是curl。

以我为例，在我试图用cURL使用的服务上安装我的证书时出现了问题。我未能将中间证书和根证书捆绑/连接到我的域证书。一开始并没有明显的问题，因为Chrome解决了这个问题并接受了证书，尽管省略了中间证书和根证书。

在捆绑证书之后，一切都按预期工作。我捆扎成这样
