您好，我正在尝试通过“do-release-upgrade”将 Ubuntu 12.04 LTS 更新到 14.04 LTS，但仍然得到：

无法在网络上获取任何信息来解决此问题。我已经将 python 2.7.3 更新为 python 2.7.11，尝试链接到 python3。还是一样的问题...

有什么想法吗？

【问题讨论】：

这将更适合询问 Ubuntu 堆栈交换。您是否正在通过 ssh 进行更新？它正在尝试启动第二个 sshd，但失败了。
通过 ssh 和直接 shell 都试过了。每次都是同样的问题。还清理了 /tmp/up*

【解决方案1】：

我已经通过直接杀死 sshd “修复”了这个问题，几乎没有通过从源代码编译重新安装 python2.7.12。

升级结束时出现一些 python 错误...升级后一切似乎都很好。
