下载 1,960 B，耗时 2分 14秒 (14 B/s)

这是我的执行结果

把下面指令 複製 貼進終端機 執行
1. sudo cat /etc/apt/sources.list
2. sudo cat /etc/os-release
把結果直接 選取/複製 貼上來

谢谢你啊，我刚解决了，我把sources.list的内容全删了，用了论坛里的163源，更新成功了
不过这样做会有什么不好的后果吗？

重點是版本是否跟你已安裝的 Ubuntu 版本是否相符

14.10(utopic) 已经停止支持和线上更新，软件源已经没有 utopic 目录
https://wiki.ubuntu.com/Releases
你使用的可能不是 14.10 源

表明你的意图
如果只想安装几个软件


如果想更新到新版
