将 Ubuntu 13.04 更新至 13.10 时出错

当我尝试将 Ubuntu 13.04 升级到 13.10 时出现以下错误：

答案1

需要注意的是，dist-upgrade 只是更新所有软件包。这个说法有点用词不当。

给这尝试一下！

简而言之，运行

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

更新所有软件包，然后

sudo apt-get install update-manager-core
sudo do-release-upgrade

实际更新至 13.10

否则，

取出您的文件（使用 Live USB/CD）并从 13.10 Live USB/CD 重新安装。
