不容易啊，学校网速慢，加上这两天有事情，好不容易才更新完毕，
Ubuntu 9.10升级Ubuntu 10.04的命令方法
sudo update-manager -d
因为好像更新后原来设置的代理没用了，所以网速非常的慢，重启一次重新设置代理了更新速度上来了。
现在更新新文件和语言补丁。
提醒的是更新完了记得换源，我现在用的这个：
deb lucid main restricted universe multiverse
deb lucid-security main restricted universe multiverse
deb lucid-updates main restricted universe multiverse
deb lucid-proposed main restricted universe multiverse
deb lucid-backports main restricted universe multiverse
deb-src lucid main restricted universe multiverse
deb-src lucid-security main restricted universe multiverse
deb-src lucid-updates main restricted universe multiverse
deb-src lucid-proposed main restricted universe multiverse
deb-src lucid-backports main restricted universe multiverse
