Ubuntu 16.04 升级到 16.10 过程中SSH中断

我猜测do-release-upgrade 一定会有恢复方案，应该是screen. 经过查看果然是 screen

开始尝试恢复screen 提示

neo@netkiller:~$ screen -ls
No Sockets found in /var/run/screen/S-neo.

后来想到应该是root而不是当前用户，再次查看

neo@netkiller:~$ sudo screen -ls
[sudo] password for neo:
There is a screen on:
1955.ubuntu-release-upgrade-screen-window(11/25/2016 07:44:50 PM) (Detached)
1 Socket in /var/run/screen/S-root.

的确如猜测一样，现在回复窗口吧。

neo@netkiller:~$ sudo screen -r 1955

继续
