Using with the .yml

---
- name: Docker Server
  hosts: "all"
  become: true
  roles:
    - role: "nickjj.docker"
      tags: ["docker"]

I got the result:

$ ansible-playbook sciencedesk-docker.yml

I maybe have been to quick opening the issue. I tried to downgrade to v1.9.2 and got the same error. However I used it some days ago and it have worked just fine.

I will gladly provide more information if required.

Just a bit more information: executing sudo apt-get update on the target host seems to solve the problem. Doesnt this role execute sudo apt-get update before try to install docker dependecies?

I am pretty new to ansible so I maybe doing something wrong.

Hi,

Typically you'd run sudo apt-get update on a host during its initial set up phase where you get Ansible ready to run on it.

This has been discussed in more detail at https://github.com/nickjj/ansible-docker/issues/73#issuecomment-582956487 for the reason why this role doesn't control running that update for you initially.
