第二、問題

2.1 403 Forbidden

This is the warning: The requested URL returned error: 403 Forbidden while accessing https://github.com

4.Save config file and quit. now you could use git push origin master to sync your repo on GitHub

so I tried this command:

git remote rm origin
git remote add origin [email protected]:eduOSS/firstGitpra.git

一般只有第一次遠程纔會繼續出現以下錯誤，因爲publickey只需要設置一次就行了

so I find the answer:

exec ssh-agent bash

Finally! After finishing the torurial I got it:
