求教！apt-get update && apt-get dist-upgrade更新，报错

     配置openstack kilo时，配置完源之后：   echo "deb http://ubuntu-cloud.archive.canonical.com/ubuntu" \
"trusty-updates/kilo main" > /etc/apt/sources.list.d/cloudarchive-kilo.list
     执行apt-get update && apt-get dist-upgrade时，更新列表最后显示：
     W: Failed to fetch cdrom://Ubuntu-Server 14.04.1 LTS _Trusty Tahr_ - Release amd64 (20140722.3)/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

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

    请问有人遇到过类似的情况吗？这种问题会对后面的配置产生影响吗？？

是不是格式错了，贴出图来看看

    格式应该没有问题。不过好像不影响后面的操作，我就没有再管它了

换成163的源就可以

应该是源的问题，换个源试试，最好是多换几个源试试。国内的几个源我都尝试过效果还是很不一样的，有些源根本找不到你想要的软件包。
