apt-get update問題。 - Linux

　　如題，以下是我下apt-get update出現的錯誤訊息。


　　W: Failed to fetch
http://archive.ubuntu.com/ubuntu/dists/lucid-security/multiverse/binary-amd64/Packages.gz
Something wicked happened resolving 'archive.ubuntu.com:http' (-5 - No
address associated with hostname)

W: Failed to fetch
http://archive.ubuntu.com/ubuntu/dists/lucid-security/multiverse/source/Sources.gz
Something wicked happened resolving 'archive.ubuntu.com:http' (-5 - No
address associated with hostname)

E: Some index files failed to download, they have been ignored, or old ones
used instead.

　　一開始我以為是ubuntu的網址掛掉了，可是去檢查還活得好好的。

　　不知道為什麼會出現最下面的那個error冏。
