你目前是 14.04 不是 15.04
要直接從 14.04 升級到 15.04 參閱
http://www.noobslab.com/2015/10/how-to- ... -wily.html
How to Upgrade To Ubuntu 15.10 Wily Werewolf From Any Ubuntu Version
從任何 Ubuntu 版本 一次到位 升級到 Ubuntu 15.10

升級 是有風險的 最好先備存
萬一失敗 才有機會重來

无法计算升级

在筹划升级时，一个不可解决问题发生了：

这可能是由以下原因造成的：
*升级为 Ubuntu 的预发行版本
*运行目前的 Ubuntu 预发布版本
*不是由 Ubuntu 提供的非官方软件包

如果这些都不生效，请在终端中使用命令 'ubuntu-bug ubuntu-release-upgrader-core' 来报告 bug。

检查不到15.10

1. 把下面指令 複製 貼進終端機 執行
1-1. sudo cat /etc/lsb-release
1-2. sudo cat /etc/apt/sources.list
1-3. sudo ls -al /etc/apt/sources.list.d
把結果直接 選取/複製 貼上來

2. 把下面指令 複製 貼進終端機 執行
2-1. sudo apt-get update
2-2. sudo apt-get upgrade
如果有錯誤訊息 請把錯誤全部複製貼上來
