今天在 update ubuntu 時一直出現

W: Failed to fetch http://tw.archive.ubuntu.com/ 


我先
 1. cd /etc/apt
 2.cpoy : sudo cp  sources.list  sources.list_back
 3.把裡面所有 http://tw.archive.ubuntu.com/   >改為 > http://us.archive.ubuntu.com/

在重新update Manager  就ok了
我原本  ubuntu 是 10.04 update 想升級為 10.10

1. sudo update-manager -d
2. 先 check  在 upgrade
3. 還是不能  update
      問題 : (一)https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/662793
                        與這篇很像,還是沒下文
            (二)Error Invalid MIT-MAGIC-COOKIE-1 key/usr/lib/pymodules/python2.6/gtk-2.0/gtk
           最後重開機 看了這篇文章
                     http://wiki.ubuntu.org.cn/index.php?title=Apt%E5%92%8Cdpkg%E5%BF%AB%E9%80%9F%E5%8F%82%E8%80%83&variant=zh-hant
                     update 一下 update-manage -d
                      最後又下載 jdk 6 就成功了..........
