cURL note

Hey User:Jlebleu, mind explaining how I can reproduce the issue that lead you to add that note? --Jhass (talk) 13:21, 16 October 2014 (UTC)

What I Did

• A wheezy basic install in a new VM (virtualbox)
• created a user diaspora with no rights and no access to sudo
• followed all installation instruction in page till curl -L dspr.tk/1t | bash
• Had the problem

diaspora@debian-wheezy:~$ curl --insecure -L dspr.tk/1t | bash

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.

• That's it

Do you maybe have some curlrc setting that enables https if no protocol is specified? --Jhass (talk) 14:19, 16 October 2014 (UTC)

I did create a new user on the same machine an tried again and did not had the same problem ....so I think we can remove the note from the wiki.--jlebleu (talk) 10:10, 17 October 2014
