Package: podman
Version: 4.3.1
Podman cannot load images compressed with gzip. Uncompressed images or
bzip2 compressed images work right therefore it seems to be a problem
related to gzip handling.
It seems to be the same problem reported here:
https://github.com/containers/podman/issues/15944
Tested under Bookworm with podman 4.3.1:
*$ podman image pull hello-world:latest*
Resolved "hello-world" as an alias
(/etc/containers/registries.conf.d/shortnames.conf)
Trying to pull docker.io/library/hello-world:latest...

*$ podman image save hello-world:latest | gzip > hello-world.tar.gz*

Attached you have the debug output of the failing command:
*$ podman --debug image load -i hello-world.tar.gz*
In Bullseye with podman 3.0.1 all works as expected:
*$ podman image pull hello-world:latest*
Resolved "hello-world" as an alias
(/etc/containers/registries.conf.d/shortnames.conf)
