A simple state like this:

Setup Fluent Bit repo:
  pkgrepo.managed:
    - humanname: Fluent Bit Repo
    - name: deb [signed-by=/etc/apt/keyrings/fluentbit-keyring.gpg] https://packages.fluentbit.io/{{ grains['osfullname']|lower }}/{{ grains['oscodename']|lower }} {{ grains['oscodename']|lower }} main
    - file: /etc/apt/sources.list.d/fluentbit.list
    - key_url: https://packages.fluentbit.io/fluentbit.key

                  deb [signed-by=/etc/apt/keyrings/fluentbit-keyring.gpg] https://packages.fluentbit.io/ubuntu/focal focal main

Additional context
Add any other context about the problem here.

Start at the pkgrepo.managed entry point and reproduce the state on Ubuntu 20.04 with aptkey set to false and the signed-by keyring path shown in the report. Trace how the repository is configured and verify that the completed behavior either creates /etc/apt/keyrings or reports a failure when that directory is absent.
