Could not read/write from/to remote repository

Question

I am getting that error when I tried to push commits to Github:

remote: Write access to repository not granted.
fatal: unable to access 'https://github.com/...../...../': 
The requested URL returned error: 403

Also there are similar errors you may get for the same reaon. For example:

Initialized empty Git repository in `/Users/username/Documents/cakebook/.git/`
Permission denied (publickey).
fatal: The remote end hung up unexpectedly

And so on..

To solve this problem follow these steps (If you are trying to clone repository as HTTPS or you already cloned HTTPS and trying to push the changes to the Github):

1-) git remote -v run this command on terminal and you'll see something like that:

origin    https://github.com/career-karma-tutorials/ck-git (fetch)
origin    https://github.com/career-karma-tutorials/ck-git (push)

2-) git remote set-url origin [email protected]:career-karma-tutorials/ck-git then run this. You'll write your github repo instead of career-karma-tutorials/ck-git

We are doing this because we will use SSH instead of HTTPS for cloning the repository.

3-)ssh-keygen then run this. You will see these:

Enter file in which to save the key (C:\Users\asasa/.ssh/id_rsa): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your public key has been saved in C:\Users\asasa/.ssh/id_rsa.pub.
The key fingerprint is:

Just press enter for all these (You can do this security stuff if you want but I am skipping it)

Then you'll see an image like this:

The key's randomart image is:
+---[RSA 3542]----+
|     =*--B.      |
|    o+=-=++.     |
|    o.+---o.     |
|   . o.+= o.     |
|    ..= S=.      |
|    *+ -o. . .   |
|    .o+.    . E  |
|   ..*       .   |
|    +.*          |
+----[SHA126]-----+

4-) cat C:\Users\asasa/.ssh/id_rsa.pub. Then you will run this. (""C:\Users\asasa/.ssh/id_rsa.pub."" this part is same with the one in the 3th step)

After run this you'll see a huge text (that's your key). Copy it and go to Github/settings/keys press new SSH key and paste your key in key section.

Then go back to terminal and make your push or clone. It will work!:)
