github上的权限被拒绝（publickey）

Question

我的工作是通过M Hartl的教程来了解Ruby on Rails。
我已经完成第6章和git push上混帐中心的工作，但我收到此错误：

rene@Linux-Ubuntu:~/rails_projets/sample_app$ git push Permission denied (publickey).
fatal: The remote end hung up unexpectedly

我重新安装一个新的公钥的帮助，Git的指令

debug1: Next authentication method: publickey 
    debug1: Offering DSA public key: rene@Linux-Ubuntu 
    debug1: Authentications that can continue: publickey 
    debug1: Offering RSA public key: rene@Linux-Ubuntu 
    debug1: Authentications that can continue: publickey 
    debug1: Trying private key: [~/.ssh/id_rsa] 
    debug1: Trying private key: [~/.ssh/id_dsa] 
    debug1: No more authentication methods to try. 
    Permission denied (publickey). 

而且我有存储库中的文件：

rene@Linux-Ubuntu:~/.ssh$ ls
ak.bak config id_dsa id_dsa.pub id_rsa id_rsa.pub key_backup/ known_hosts

我做错了什么？

你有没有告诉github你的公钥？
