How is the image produced, can please provide a full reproducer?

[paulomorgado]

This won't show the issue, because the tar file will only have the manifest.json file and not an index.json file:

podman save --multi-image-archive -o combined_images.tar mcr.microsoft.com/dotnet/sdk:8.0 mcr.microsoft.com/dotnet/sdk:9.0
load -i combined_images.tar

The tar file I was loading had a index.json file with the full image names.

I'm trying to get a repro.

[paulomorgado]

Looks like the tar file was created with Docker Desktop.

But I tried:

docker save -o combined_images.tar mcr.microsoft.com/dotnet/sdk:8.0 mcr.microsoft.com/dotnet/sdk:9.0
podman load -i combined_images.tar

And it didn't repro.
