I can not install the discourse.
When I try to start I see this:
```plaintext
root@s9ffd138e:/var/discourse# ./launcher start app
Device "docker0" does not exist.
Cannot connect to the docker daemon - verify it is running and you have access
root@s9ffd138e:/var/discourse# ./launcher rebuild app
Device "docker0" does not exist.
Cannot connect to the docker daemon - verify it is running and you have access
```
The installation was done according to this instruction [discourse/docs/INSTALL-cloud.md at main · discourse/discourse · GitHub](https://github.com/discourse/discourse/blob/master/docs/INSTALL-cloud.md)

Your docker install is bad.
You can try starting the service with `service docker start`.
Or a new install following: [Install Docker Engine on Ubuntu | Docker Docs](https://docs.docker.com/engine/installation/linux/docker-ce/ubuntu/)

Here such error takes off,
```
:/var/discourse# service docker start
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

As Falco said, your docker install is bad. Real bad.

I tried to reinstall. I tried setting a discourse on ubuntu 16.04 and ubuntu on 14.04. And everywhere one problem. I do not run the docker according to the instructions.

Then you are on your own. We have enough trouble keeping up with Docker weirdnesses when people stick to the straight and narrow. You might be able to get some knowledgeable help at [https://forums.docker.com](https://forums.docker.com).
