Fix git push fail v2

Several months ago, I wrote a blog about how to Fix-git-push-fail.

But now, I acidentally found that I didn’t spelled my email address correctly in the git config (Because I found that I can’t access a newly create private repo on GitHub, and the commit user seems differ from the one I farmiliar with).
Which caused conflict between my local ssh key and the one in the GitHub account.

So, a easier way to fix this problem is to change git config

git config --global user.email "your_email@example.com"
git config --global user.name "your_name"

And we may also need to point to the correct ssh key for github.

vi ~/.ssh/config

Add the following content:

Host github.com
	HostName github.com
	IdentityFile=/home/dyliu/.ssh/id_ed25519_gmail

We can try

ssh -T git@github.com

to test if the ssh key is correct.
