Compose: Installing docker-compose killed docker

[gregfr]

Description of the issue

I've installed a fresh Ubuntu 18.04, then docker from repos, then a few containers. Everything was doing fine.
I've then installed docker-composer from repos : docker is now dead, I can't start it, even after rebooting.

Context information (for bug reports)

Output of "docker-compose version"

docker-compose version 1.17.1, build unknown
docker-py version: 2.5.1
CPython version: 2.7.15rc1

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

Everything was done as root, so I don't think it's a permission problem.
I've done some googling but didn't find any solution.

Is there a way to get thing back online without re-installing everything?

Thanks

I removed completely docker and docker-compose, and re-installed only docker, still dead.

Did you install docker-compose from the Ubuntu repository? (ie, a version that's packaged by Ubuntu?)

I wonder if doing so also resulted in the Ubuntu packaged version of Docker to be installed (given that that would be a conflicting package, possibly that resulted in your existing version of Docker to be uninstalled)

Closing, but please update if you're still seeing issues. As @thaJeztah pointed out, distro packages can cause some problems - refer to our documentation for the supported install options: https://docs.docker.com/compose/install/

fwiw i just ran into this:

• first installed docker.io on ubuntu 16.04
• used it long time with systemd enabled service for the daemon, no problems
• upgraded to 18.04
• continued using with no problems
• now wanted to add docker-compose
• see problem above

My theory atm:
docker-compose possibly maskes the docker.io systemd unit file (links it to /dev/null), purging docker.io and docker-compose does not remove this link. after reinstalling docker-compose, problem persists.

Solution:
once i did 'rm /etc/systemd/system/docker.service' i could manage the service via 'systemctl'

i'm not sure how this happens, it might be related to the still existing SysV init-files for the package, and how they get handled in conjunction with 18.04 and possibly 16.04

it's all pretty weird.

same thing with me too ,installed docker-compose and docker daemon wont start

@whysthatso Just ran into this issue, could you please describe the full solution step by step? Do I need to uninstall docker-compose and stuff and then reinstall docker or what?

as far as i remember:

• uninstall everything docker-related
• check if there is /etc/systemd/system/docker.service, delete it
• install docker-compose

or it could be:

• uninstall everything docker-related

but yeah, sorry, i realized i should have contextualized my comment a bit better

• install docker-compose
• check if there is /etc/systemd/system/docker.service, delete it

try both, can't really mess anything up here

[Nixellion]

@whysthatso Thanks, I actually solved it. The main point is to make sure to isntall Docker CE and Compose from appropriate repositories, not from distro's repos

I have same problem. Installing docker-compose killed running docker daemon. How sad there is no standard repo for Ubuntu for both docker and docker-compose. I found the following link that explains the two alternative universes for docker on Debian (docker.io vs docker-ce):

https://www.collabora.com/news-and-blog/blog/2018/07/04/docker-io-debian-package-back-to-life/

I lean toward installing docker-ce as opposed to docker.io, hence follow these two guides:

https://docs.docker.com/install/linux/docker-ce/ubuntu/ (includes uninstall docker.io package)

https://docs.docker.com/compose/install/
