Raspberry Pi 3上的Ubuntu Core 16無法連接到Docker守護進程

設置完新鮮的Ubuntu Core 16 Raspberry Pi機器後。使用來自Ubuntu Core的圖像web page。Raspberry Pi 3上的Ubuntu Core 16無法連接到Docker守護進程

並在其上安裝泊塢窗帶止：

snap install docker

我不能夠使用泊塢窗，我得到一個錯誤：

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

泊塢窗服務狀態是無效的（死）：

sudo systemctl status snap.docker.dockerd.service 

snap.docker.dockerd.service - Service for snap application docker.dockerd 
Loaded: loaded (/etc/systemd/system/snap.docker.dockerd.service; enabled; vendor preset: enabled) 
Active: inactive (dead) (Result: exit-code) since Wed 2017-05-03 10:30:55 UTC; 30min ago 
Process: 1975 ExecStart=/usr/bin/snap run docker.dockerd (code=exited, status=126)

May 03 10:30:55 localhost.localdomain systemd[1]: Stopped Service for snap application docker.dockerd.

May 03 10:30:55 localhost.localdomain systemd[1]: Failed to start Service for snap application docker.dockerd.

重新啓動碼頭服務：

sudo systemctl stop snap.docker.dockerd.service 
sudo systemctl start snap.docker.dockerd.service

沒有幫助。

泊塢版本輸出：

Client: 
Version:  1.13.1 
API version: 1.26 
Go version: go1.7.5 
Git commit: -snap-a2d8d8c 
Built:  Fri Apr 21 08:56:55 2017 
OS/Arch:  linux/arm 
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

的搬運工捕捉連接：

snap interfaces |grep docker 

:docker-support   docker:privileged,docker:support 
:firewall-control   docker 
:network     docker 
:network-bind    docker 
docker:docker-daemon  docker:docker-cli 
-       docker:account-control 
-       docker:home

有沒有正常啓動碼頭工人守護進程所需的任何額外的步驟？

UPD：碼頭工人服務日誌

sudo journalctl -u snap.docker.dockerd.service -f

有一個在這個郵件列表中發佈一些有用的信息，這可能會有幫助。特別是關於首先刪除debs的那個。你看到了嗎？ https://lists.ubuntu.com/archives/snapcraft/2016-October/001382.html – popey

這些消息表明docker守護進程提前退出。下一步就是找出其日誌所說的內容。 –

我有同樣的問題，因爲你，但有它在執行給定this post的命令後再次合作。

這些命令：

$ sudo snap connect docker:account-control :account-control 
$ sudo snap connect docker:home :home 
$ snap disable docker && snap enable docker 
$ newgrp docker-snap
