更新信息已过时(通知图标)

我正在运行 Ubuntu 14.10 服务器

尽管软件中心正在正确运行更新并且我没有新的可用更新,但过去几天我仍在通知栏中看到此图标。

我运行了sudo apt-get update && sudo apt-get upgrade还是有这个问题,
运行后的输出sudo apt-get update是:

W: Failed to fetch cdrom://Ubuntu-Server 14.10 _Utopic Unicorn_ - Release i386 (20141022.2)/dists/utopic/main/binary-i386/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-Server 14.10 _Utopic Unicorn_ - Release i386 (20141022.2)/dists/utopic/restricted/binary-i386/Packages  Please use apt-cdrom to make this CD-ROM recognized by APT. apt-get update cannot be used to add new CD-ROMs

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

我该如何修复此问题?

答案1

单击 Unity 仪表板(或其他菜单系统)并打开“软件源”(有时也称为“软件和更新”)。然后您需要做的是转到“其他软件”选项卡,取消选中列出 cdrom 的选项。然后单击应用,再次更新,这样应该可以解决问题
