With a config like this:
jobs:
e2e-build:
machine:
image: ubuntu-2004:202111-02
steps:
- checkout
There's an error like:
Unable to find image 'ubuntu-2004:202111-02' locally
docker: Error response from daemon: pull access denied for ubuntu-2004, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.
This happens with several ubuntu-* images.
Maybe logging into Docker is needed.
