question
A virtual machine of mine is ubuntu, docker is installed when install ubuntu from iso. After that, I installed again from apt, because previous one is not registered in "systemctl". Now , there is two space for both docker, just like following.
Two docker have their own space for "docker ps / image CMD" .
Reboot start with "SPACE docker A", and "systemctl status" works good. Once "systemctl restart", move to "SPACE docker B".
If I want remove "SPACE docker A". How can I do it? I would be very grateful if any suggestion is given.
For now, my workaround is manually systemctl restart every time.

As you can see docker daemon is not among the running processes, but the docker. service is active and I am pretty sure all permissions have been set correctly. So what can I do here?
I run
systemctl status docker
and get

ERROR: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
errors pretty printing info
Does anyone know what's wrong here?
(i do see a docker.pid in /var/run, however i do NOT see a docker.sock in /var/run)
After further discovery, the socket file is here
/run/docker.sock
not /var/run/docker.sock
the systemd unit file for docker.socket looks like
cat docker.socket
[Unit]
Description=Docker Socket for the API
[Socket]
ListenStream=/var/run/docker.sock
SocketMode=0660
SocketUser=root
SocketGroup=docker
[Install]
WantedBy=sockets.target
not sure if the daemon or the client is wrong, and how to fix it???
UPDATE: hmm it seems if i create a symlink from /var/run/docker.sock to /run/docker.sock it works. Not great, but i guess i'll live with it
I can't restart docker service. After command system just getting stuck.

What can I check?
I'm trying to pull an image off GCR using docker, using:
docker pull eu.gcr.io/<project>/<image>:<tag>
However I keep getting the error:

After receiving the error all calls to docker returns:

I've tried restarting docker but to no avail. Any help is much appriciated.
Following this article on Jhipster, I build the project. I, however, can't run docker-compose. So, I try to figure out the problem. I walk step by step with this Docker-Compose article without luck.

ERROR: Couldn't connect to Docker daemon at http+docker://localhost - is it running?
If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.
The result of the last step is the same as "docker-compose up -d". According to the article, it would be a permission problem if the problem still exists at this point. How can I find what permission issue?
There are multiple ways you can solve this problem. Firstly try to export environment variable of docker host with command:
export DOCKER_HOST=/var/run/docker.sock
If it works you can add the same line to your bashrc config to save this export permanently.
If it doesn't work you can try to modify docker daemon config. It located in
/etc/docker/daemon.json
You'll need to append the localhost to your hosts like that:
"hosts": ["old_hosts_not_modified_only_append_new_one", "tcp://localhost:2376"],
and restart docker daemon using command:
service docker restart
Hope it gonna help ya
