Describe the bug

dnf hangs when doing a two stage build of keycloak to include curl on running scriplet glibc-2.34-125.el9_5.3.x86_64.

This works properly on a Windows machine but fails on AWS Linux 2 server. I have tried multiple AWS servers, all fail.

# create builder image with curl properly installed
FROM registry.access.redhat.com/ubi9 AS ubi-micro-build
RUN mkdir -p /mnt/rootfs
RUN dnf clean all  # troubleshooting step
RUN dnf upgrade # troubleshooting step
RUN dnf install --installroot /mnt/rootfs curl --releasever 9 --setopt install_weak_deps=false --nodocs -y && \

dnf --installroot /mnt/rootfs clean all && \
rpm --root /mnt/rootfs -e --nodeps setup

# starting with base keycloak image
FROM quay.io/keycloak/keycloak:26.1
# copy from build image to custom image
USER root
COPY --from=ubi-micro-build /mnt/rootfs /

# continue with snc specific files
USER 1000

RUN mkdir /opt/keycloak/data/import
COPY snc-export.json /opt/keycloak/data/import

I can't include errors as the process never completes. I let it run for 10 minutes. Here is a screen shot of the process hanging.
