I put this tips here because every time I need to pull a project from github, where I'm not contributor, I've certificates problem and I always dismembered the solution :D
[root@centos564 ~]# git clone https://github.com/onelogin/python-saml.git Cloning into python-saml... error: SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed while accessing https://github.com/onelogin/python-saml.git/info/refs fatal: HTTP request failed
The solution, without install of certificate somewhere on the local machine, is:
[root@centos564 ~]# env GIT_SSL_NO_VERIFY=true git clone https://github.com/onelogin/python-saml.git Cloning into python-saml... remote: Counting objects: 27, done. remote: Compressing objects: 100% (24/24), done. remote: Total 27 (delta 3), reused 25 (delta 1) Unpacking objects: 100% (27/27), done.
