git push仅在`sudo`下有效

Question

When I try to push a git repository to github :

julia_proj git:(master) git push -u origin master
fatal: unable to access 'https://github.com/nickleeh/julia_proj.git/': SSL certificate problem: unable to get local issuer certificate

I tried to use sudo :

julia_proj git:(master) sudo git push -u origin master
[sudo] password for nick: 
Username for 'https://github.com': nickleeh
Password for 'https://nickleeh@github.com':

To https://github.com/nickleeh/julia_proj.git
 * [new branch]      master -> master
Branch master set up to track remote branch master from origin.

I'm so surprised that it works under sudo , (it also require me to input github account name and password.) What's wrong here and how can I set up this without using sudo ?

Software environment:

➜  julia_proj git:(master) uname -a
Linux nick-thinkpad 4.2.5-1-ARCH #1 SMP PREEMPT Tue Oct 27 08:13:28 CET 2015 x86_64 GNU/Linux
➜  julia_proj git:(master) git --version
git version 2.6.4
➜  julia_proj git:(master)

Once you have determined which certificates file (as mentioned by Guildencrantz ) you are using:

 curl -sv https://github.com/ 2>&1 >/dev/null | grep 'CAfile'

do (without sudo)

cd /path/to/your/local/repo
git config http.sslCAInfo /path/to/certificates

If the push works, set that for all repos:

cd /any/path/you/want
git config --global http.sslCAInfo /path/to/certificates
