I found the cause.
ctx -> ir.ClientCtx

I am working on it and will open a PR.

podman/pkg/domain/infra/tunnel/manifest.go

Lines 202 to 216 in 092d040

 // ManifestListClear clears out all instances from a manifest list 

 func (ir *ImageEngine) ManifestListClear(ctx context.Context, name string) (string, error) { 

 listContents, err := manifests.InspectListData(ctx, name, &manifests.InspectOptions{}) 

 if err != nil { 

 return "", err 

 } 

 for _, instance := range listContents.Manifests { 

 if _, err := manifests.Remove(ctx, name, instance.Digest.String(), &manifests.RemoveOptions{}); err != nil { 

 return "", err 

 } 

 } 

 return name, nil 

 }

from podman.

I now know why this issue slipped through the test.

Even with the current code, the first podman farm build succeeds in a clean test environment. This is because it simply pushes the generated manifest.

However, the second run requires deleting the existing manifest in the registry, which is not possible with the current code.

Along with modifying the code, the test needs to be modified so that the command is executed more than once.
