podman has postinst elog messages instructing users to copy the example configuration into /etc/containers/registries.conf: elog "You need to create the following config files:" elog "/etc/containers/registries.conf" elog "/etc/containers/policy.json" elog "To copy over default examples, use:" elog "cp /etc/containers/registries.conf{.example,}" elog "cp /etc/containers/policy.json{.example,}" The installed example configuration comes from https://github.com/containers/podman/blob/main/test/registries.conf Attempting to use this registries.conf seems to not work as expected: # podman system reset -f && cp /etc/containers/registries.conf{.example,} # podman pull registry ✔ docker.io/library/registry:latest Trying to pull docker.io/library/registry:latest... Error: initializing source docker://registry:latest: reading manifest latest in quay.io/libpod/registry: manifest unknown: manifest unknown However, this is successful if each of the [[registry]] sections are commented out in /etc/containers/registries.conf, which seems to be roughly similar to Debian's default registries.conf. Further, I'm not sure a configuration from the 'tests' directory is suitable for distributions to ship as "default" configuration (as an example, this configuration references a local registry for testing purposes: https://github.com/containers/podman/blob/main/test/registries.conf#L21). Am I missing something here?
