podman/unknown,now 100:3.0.1-2 amd64 [installed]

Note, I discovered this issue on version 3.0.1 and could replicate it with the static build from this ci run.

Have you tested with the latest version of Podman and have you checked the Podman Troubleshooting Guide?

Yes

same with podman-remote. I looked at the code, but I don’t know how to modify it with minimal intervention @rhatdan PTAL

[arctic-alpaca]

I just noticed another thing, when using podman info --format="json", the response is missing the exists field in the remoteSocket object.

this is not a bug. only display when the sock file is exists

Is this intended? Shouldn't it be

{
  "path": "/run/podman/podman.sock",
  "exists": false
}

if the file doesn't exist?
