有安装有ubuntu 8.04 服务器版的没有，apt-get update可以升级吗

我的服务器是在vmware虚拟机下安装的，上网正常，
命令行下
用的源
deb http://mirror.bjtu.edu.cn/ubuntu/ hardy main restricted universe multiverse
deb http://mirror.bjtu.edu.cn/ubuntu/ hardy-backports restricted universe multiverse
deb http://mirror.bjtu.edu.cn/ubuntu/ hardy-proposed main restricted universe multiverse
deb http://mirror.bjtu.edu.cn/ubuntu/ hardy-security main restricted universe multiverse
deb http://mirror.bjtu.edu.cn/ubuntu/ hardy-updates main restricted universe multiverse
deb-src http://mirror.bjtu.edu.cn/ubuntu/ hardy main restricted universe multiverse
deb-src http://mirror.bjtu.edu.cn/ubuntu/ hardy-backports main restricted universe multiverse
deb-src http://mirror.bjtu.edu.cn/ubuntu/ hardy-proposed main restricted universe multiverse
deb-src http://mirror.bjtu.edu.cn/ubuntu/ hardy-security main restricted universe multiverse
deb-src http://mirror.bjtu.edu.cn/ubuntu/ hardy-updates main restricted universe multiverse

命令行更新源如下
root@ubuntu:/etc/apt# apt-get update
Err http://mirror.bjtu.edu.cn hardy Release.gpg

老是忽略ign 和err ，下面的4% 一直在涨，就是很慢，这是更新了，还是没有更新啊，
