真的是闭门家中坐，祸从天上来。前两天闲来无事就点了一下upgrade，然后，apt-get工具抛锚了，问题如下：
ttt@ttt:/home$ sudo apt upgrade

dpkg: error processing package docker-ce (--configure):
subprocess installed post-installation script returned error exit status 1
dpkg: dependency problems prevent configuration of nvidia-docker2:
nvidia-docker2 depends on docker-ce (= 5:18.09.1~3-0~ubuntu-xenial) | docker-ee (= 5:18.09.1~3-0~ubuntu-xenial); however:
Package docker-ce is not configured yet.
Package docker-ee is not installed.
dpkg: error processing package nvidia-docker2 (--configure):
dependency problems - leaving unconfigured
No apport report written because the error message indicates its a followup error from a previous failure.
Errors were encountered while processing:

E: Sub-process /usr/bin/dpkg returned an error code (1)
解决方案：
重新安装docker-ce
由于之前安装过，什么证书啊啥的都有，比重头安装要简单些，当然也可以参考官网。下面是我的修复过程
$ sudo apt-get purge -y docker-ce
$ sudo apt-get install docker.io
$ sudo apt upgrade
$ sudo apt install nvidia-docker
$ sudo apt autoremove
应该是官方打补丁是么步骤不对，才导致这个问题，问题不大，在网上找了点资料，手动修复下就好了。
