未能从14.04升级到14.10

我一直都在上网。我可以下载几个包，而不是下载停止，我得到了下一个消息：

Could not download the upgrades

尝试从另一个镜像下载：

GUI

• 开放软件中心
• 点击:编辑>软件资源
• 找到下拉菜单“下载”
• 选择其他
• 选择一面镜子

命令行

• 打开/etc/apt/sudo.列表(sudo nano /etc/apt/sudo.nano)
• 定位http://XX.archive.ubuntu.com/ubuntu
• 用另一个令牌http://YY.archive.ubuntu.com/ubuntu替换它

您还可以使用此工具生成自定义的sources.list：http://repogen.simplylinux.ch/
