如何纠正 xubuntu 12.04 中 sudo apt-get update 的错误

当我sudo apt-get update在 xubuntu 12.04 中运行时，它给出：

Hit http://archive.canonical.com precise Release.gpg                                                          
Err http://archove.canonical.com precise Release.gpg                                                          
  Something wicked happened resolving 'archove.canonical.com:http' (-5 - No address associated with hostname)

The error msg repeats

Err http://archove.canonical.com precise/partner Sources

The program terminates with the msg

Err http://archove.canonical.com precise/partner Translation-en_US
