Installation failure with Docker 20.10.6 on Debian GNU/Linux 11 (bullseye)

[jonathantullett]

Hello,

I am using this role to install docker onto a raspberry pi 4, 64Bit install. This is the playbook

$ cat playbooks/install-docker-skelton.yml
---
- hosts: docker_rpi
  become: yes
  vars:
    docker_compose_version: 1.29.2
    docker_version_arm64: 5:20.10.6~3-0~debian-bullseye

    pip_package: python3-pip
    pip_executable: pip3
    pip_install_packages:
      - name: setuptools
      - name: docker
      - name: docker-compose

  roles:
    - geerlingguy.pip
    - geerlingguy.docker_arm

And the output is:

PLAY [docker_rpi] ************************************************************************************************************************************************************************************************

TASK [Gathering Facts] *******************************************************************************************************************************************************************************************
ok: [tn4pi02]

TASK [geerlingguy.pip : Ensure Pip is installed.] ****************************************************************************************************************************************************************
fatal: [tn4pi02]: FAILED! => {"changed": false, "msg": "E:Conflicting values set for option Signed-By regarding source https://download.docker.com/linux/debian/ bullseye: /usr/share/keyrings/docker-archive-keyring.gpg != , E:The list of sources could not be read."}

Checking the local filesystem:

# cat /etc/apt/sources.list.d/docker.list 
deb [arch=arm64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/debian bullseye stable

And comparing the key here with https://download.docker.com/linux/debian/gpg:

9f3702d8745994675fc9003c6e2b5b26  /usr/share/keyrings/docker-archive-keyring.gpg
1afae06b34a13c1b3d9cb61a26285a15  /dev/fd/63

So they are indeed different.

I've seen this related issue open, but am unsure how to wrangle that into this role

Is there a quick fix for this? Thanks very much, Jonathan.

I've just repeated the process on a fresh install, and see the same thing. /etc/apt/sources.list.d has nothing docker related in it, then the playbook runs:

Thanks for any help you can provide.

I have upgraded the galaxy role from v4.0.0 to v5.0.0 to no avail. Now out of ideas myself.

I'm going to close this now. After a few goes of getting funky inconsistencies, I rebooted the device and now it's run successfully first time. I'll revisit on my next build, should it occur again.
