私はwgetを使用して、リモートサーバー(ssh)経由でgithubからファイルを取得しようとしています。
$ wget https://raw.githubusercontent.com/aseemk/seadragon-ajax/master/seadragon-min.js

Curlについても同じことが言えます。
$ 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.
Wgetオプションの使用:--no-check-certificate
はハックのように思えますが、何が欠けているのでしょうか?
解決策はシンプルで、私のdebianシステムからインストールするだけです:
$ Sudo apt-get install ca-certificates
Raspbianでこの問題が発生しました。次の方法で修正しました。
Sudo apt-get install ssl-cert
