error listing models: %w

Error message

error listing models: %w

What it means

listDockerModels executes `docker model list --json` inside the VM via guest.RunOutput and a non-zero exit surfaces here. Typical roots: the VM's docker engine/CLI lacks the model subcommand (older Docker), the docker daemon is unreachable inside the VM, or the call was made without the prerequisite checks (VM running) having passed.

Solutions

1. See the real error by running it in the VM: colima ssh -- docker model list --json
2. Upgrade the VM's docker engine (colima stop && colima start --upgrade) so the model plugin exists
3. Always enter through the public paths that call validateCommonPrerequisites first (VM running, docker runtime, krunkit)

// probe plugin availability before parsing-dependent flows
if _, err := guest.RunOutput("docker", "model", "--help"); err != nil {
	return nil, fmt.Errorf("docker model plugin not available in VM: %w", err)
}

When it happens

Trigger: Docker version in the colima VM predates `docker model`; docker daemon wedged or still initializing inside the VM; invoking listDockerModels directly, bypassing validateCommonPrerequisites.

Common situations: Older colima VM images carrying older Docker; commands run right after colima start while dockerd is not yet ready.
