取得 Trusty 失敗？

所以這是我的問題，我每隔一段時間就會更新一次，但這次不同，它會拋出一個錯誤：

W: Failed to fetch cdrom://Ubuntu-GNOME 14.04.1 LTS _Trusty Tahr_ - Release amd64 (20140722.2)/dists/trusty/main/binary-amd64/Packages  Please use apt-cdrom to make this CD-ROM recognized by APT. apt-get update cannot be used to add new CD-ROMs

W: Failed to fetch cdrom://Ubuntu-GNOME 14.04.1 LTS _Trusty Tahr_ - Release amd64 (20140722.2)/dists/trusty/restricted/binary-amd64/Packages  Please use apt-cdrom to make this CD-ROM recognized by APT. apt-get update cannot be used to add new CD-ROMs

W: Failed to fetch http://ppa.launchpad.net/sun-java-community-team/sun-java6/ubuntu/dists/trusty/main/binary-amd64/Packages  404  Not Found

W: Failed to fetch http://ppa.launchpad.net/sun-java-community-team/sun-java6/ubuntu/dists/trusty/main/binary-i386/Packages  404  Not Found

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

我希望有人能提供幫助，無論如何謝謝。
