用代理上網(wǎng)的話，
apt加上代理：vi /etc/apt/apt.conf

把文件中的”false”改為”http://yourproxyserver:port”。

升級(jí)

apt-get update

apt-get upgrade

升級(jí)內(nèi)核
apt-get install linux-686

更新完后重啟，發(fā)現(xiàn)grub里還有原來(lái)的i386的kernel在，自然不再需要了：

sudo vi /boot/grub/menu.lst

把里面386的normal和recovery項(xiàng)目都刪除咯。

完工！！
