Ubuntu systemd[1]: docker.service: Job docker.service/start failed with result 'dependency'

Docker Engine General

I am running Ubuntu 20.04 to run a dockerized NextCloud installation. Usually, I just need to run

$ docker-compose pull
$ docker-compose up -d

to update my containers but now I ran into the following error:

# service docker status

● docker.service - Docker Application Container Engine

Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)

I tried to re-install docker but that did not resolve the problem. When running

apt-get install docker-ce

I obtain the above mentioned error.

Any idea how to continue?

I ran in to this after upgrading to Ubuntu 20.04 and I purged “unused” settings with the command:

apt purge `dpkg --list | grep ^rc | awk '{ print $2; }'`

This disabled docker.

I resolved it with the command:

sudo systemctl enable --now docker
