Ubuntu12.04_X64 apt-get install 报错404

apt-get install gcc

 不能正确安装, 最后错误显示如下:

root@production2:~# 

 查看/etc/apt/sources.list

root@product:~# ls /etc/apt/
apt.conf.d     sources.list           sources.list.d        trustdb.gpg  trusted.gpg.d
preferences.d  sources.list.20130930  sources.list.english  trusted.gpg

 是配置的http://cn.archive.ubuntu.com/ubuntu/;

deb http://cn.archive.ubuntu.com/ubuntu/ precise main restricted universe multiverse
deb http://cn.archive.ubuntu.com/ubuntu/ precise-security main restricted universe multiverse
deb http://cn.archive.ubuntu.com/ubuntu/ precise-updates main restricted universe multiverse
deb http://cn.archive.ubuntu.com/ubuntu/ precise-proposed main restricted universe multiverse
deb http://cn.archive.ubuntu.com/ubuntu/ precise-backports main restricted universe multiverse
deb-src http://cn.archive.ubuntu.com/ubuntu/ precise main restricted universe multiverse
deb-src http://cn.archive.ubuntu.com/ubuntu/ precise-security main restricted universe multiverse
deb-src http://cn.archive.ubuntu.com/ubuntu/ precise-updates main restricted universe multiverse
deb-src http://cn.archive.ubuntu.com/ubuntu/ precise-proposed main restricted universe multiverse
deb-src http://cn.archive.ubuntu.com/ubuntu/ precise-backports main restricted universe multiverse

 网上查询了一下路径, 此路径是正确的.

 

所以最后更新一下源.

sudo apt-get update

再安装gcc, 正确了安装,
