错误:`raw.githubusercontent.com'的证书不受信任

Question

我试图使用wget通过远程服务器(ssh)从github检索一些文件,这是我得到的:

$ wget  https://raw.githubusercontent.com/aseemk/seadragon-ajax/master/seadragon-min.js
--2014-11-26 09:30:14--  https://raw.githubusercontent.com/aseemk/seadragon-ajax/master/seadragon-min.js
Resolving raw.githubusercontent.com (raw.githubusercontent.com)... 185.31.19.133
Connecting to raw.githubusercontent.com (raw.githubusercontent.com)|185.31.19.133|:443... connected.
ERROR: The certificate of `raw.githubusercontent.com' is not trusted.
ERROR: The certificate of `raw.githubusercontent.com' hasn't got a known issuer.

同样适用于卷曲:

$ curl -o bla  https://raw.githubusercontent.com/aseemk/seadragon-ajax/master/seadragon-min.js

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wget选项:--no-check-certificate看起来像一个黑客,我可以缺少什么？

解决方案很简单,从我的debian系统中简单安装:

$ sudo apt-get install ca-certificates
