download command produces wrong container names when using oci registry

[katexochen]

I'm trying to archive packages in a container registry and download them afterwards with repro-get to then export them. The naming/urls of the downloaded packages seem to be wrong in the cache, and an export fails. If I pull the images with oras, they have the expected names.

Containerfile to get apk packages:

FROM alpine:3.17.1 as builder
ADD https://github.com/reproducible-containers/repro-get/releases/download/v0.3.0/repro-get-v0.3.0.linux-amd64 \
    /usr/bin/repro-get
RUN chmod +x /usr/bin/repro-get
RUN apk update && apk add bash
WORKDIR /out
RUN repro-get hash generate > /out/SHA256SUMS
RUN repro-get cache export /out/repository-apk

FROM scratch
COPY --from=builder /out .

Commands to get apks and push to registry:

DOCKER_BUILDKIT=1 docker build -o . -f ../Containerfile .
cd out/repository-apk
oras push ghcr.io/katexochen/apk-repo-test:latest *.apk

Trying to pull the image with repro-get:

$ repro-get \
    --provider=oci://ghcr.io/katexochen/apk-repo-test \
    --cache ./cache \
    --distro alpine \
    download SHA256SUMS-apk-amd64
