问题
I am trying to use wget to retrieve some file from github over a remote server (ssh), here is what I get:
$ 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.
Same goes for curl:
$ 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.
Using wget option: --no-check-certificate seems like a hack, what could I be missing ?
回答1:
The solution was simple, from my debian system simply install:
$ sudo apt-get install ca-certificates

I had this problem on raspbian, fixed it with:
sudo apt-get install ssl-cert
