# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 127.0.1.1

1. 這個套件庫 只有使用在 安裝時 安裝後應該會自動改為
# deb cdrom:[Ubuntu 14.10 _Utopic Unicorn_ - Release amd64 (20141022.1)]/ trusty main multiverse restricted universe
1-1. 如果 安裝後還要從這個套件庫 下載套件來安裝 (一般使用沒有網路連接情況)
需要 改回
deb cdrom:[Ubuntu 14.10 _Utopic Unicorn_ - Release amd64 (20141022.1)]/ trusty main multiverse restricted universe
然後把其它連網的套件庫前面加上 # (因為沒有網路連接情況)
例如
# deb http://cn.archive.ubuntu.com/ubuntu/ utopic main restricted
# deb-src http://cn.archive.ubuntu.com/ubuntu/ utopic main restricted
需要把 Ubuntu Live CD/DVD/USB 插入 並且執行
sudo apt-get update
才能開始下載安裝
1-2. 安裝完畢 需要把 上面 1-1 的更改 恢復原狀 並且執行
sudo apt-get update


2. 原因是 沒有其它 nameserver 設定 無法解析 domain name

4. 溫馨提示
修改完上面的各點
需要先
sudo apt-get update
才生效

非常感谢您的耐心回复
我消化一下 十分感谢
