我试图把我的一个项目推到github，我一直得到这个错误:

peeplesoft@jane3:~/846156 (master) $ git push

fatal: The current branch master has no upstream branch.
To push the current branch and set the remote as upstream, use

     git push --set-upstream origin master

所以我试了一下，得到了这个:

peeplesoft@jane3:~/846156 (master) $ git push --set-upstream origin master

fatal: Authentication failed

另一个stackoverflow线程建议我尝试以下方法，但结果令人失望。

peeplesoft@jane3:~/846156 (master) $ git push -u origin master

fatal: Authentication failed

然后我试了一下:

peeplesoft@jane3:~/846156 (master) $ git config remote.origin.push HEAD

peeplesoft@jane3:~/846156 (master) $ git push

fatal: Authentication failed

有提示吗?
