Docker on Raspbian unable to pull

Can you please share the following details?

  1. How did you install Docker? Sharing the platform almost answers it, but only almost. Direct links to the followed guide can be useful.

  2. On debian based Linux, the following commands can give us some idea and recognize incorrectly installed Docker:

    docker info
    docker version
    

    Review the output before sharing and remove confidential data if any appears (public IP for example)

    dpkg -l 'docker*' | grep '^ii'
    snap list docker
    

    When you share the outputs, always format your posts according to the following guide: How to format your forum posts

If it is not a machine in your network, it is like Docker is running in an isolated network already, but I still can’t tell you see that IP as I don’t remember that either. The information I asked for above should help us to recognize something that brings us closer to the solution.
