有一些索引文件不能下载，它们可能被忽略了，也可能转而使用了旧的索引文件。

 

是源的问题，我重新换了一个源就ok了！
具体操作如下：
首先备份原来的源文件：

代码:

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

然后，编辑原来的源文件：

代码:

sudo gedit /etc/apt/sources.list

然后，将文件里的内容全部删除，替换为以下源：

代码:

#网易（速度很快）
#代码:
deb http://mirrors.163.com/ubuntu/ lucid main universe restricted multiverse
deb-src http://mirrors.163.com/ubuntu/ lucid main universe restricted multiverse
deb http://mirrors.163.com/ubuntu/ lucid-security universe main multiverse restricted
deb-src http://mirrors.163.com/ubuntu/ lucid-security universe main multiverse restricted
deb http://mirrors.163.com/ubuntu/ lucid-updates universe main multiverse restricted
deb http://mirrors.163.com/ubuntu/ lucid-proposed universe main multiverse restricted
deb-src http://mirrors.163.com/ubuntu/ lucid-proposed universe main multiverse restricted
deb http://mirrors.163.com/ubuntu/ lucid-backports universe main multiverse restricted
deb-src http://mirrors.163.com/ubuntu/ lucid-backports universe main multiverse restricted
deb-src http://mirrors.163.com/ubuntu/ lucid-updates universe main multiverse restricted

最后保存退出，保存后输入下面的指令刷新源信息：

代码:

sudo apt-get update

然后输入：

代码:

sudo apt-get upgrade

就可以进行系统升级了。
