Package installation on containers using the custom repository "Hashicorp" in RHEL 8 failed.

Version-Release number of selected component (if applicable):

How reproducible:
100%


Steps to Reproduce:

1) Log into the satellite web UI.
2) Create a content credential called "Hashicorp" of type "GPG Key" in Content-> Content Credentials; paste the "Hashicorp" public key from
   https://rpm.releases.hashicorp.com/gpg
3) Create a product called "Custom" in Content -> Products
4) Create a repository on the Repositories tab called "Hashicorp", with type "yum",
   Upstream URL "https://rpm.releases.hashicorp.com/RHEL/8/x86_64/stable" and GPG key
   "Hashicorp"
5) Change the Download Policy to "On Demand".
6) Sync the repository by selecting it and clicking "Sync Now"
7) Create a content view "Test" and Add the "Hashicorp" repository to it on the Yum Content tab.
8) Click "Publish New Version" and wait for it to finish.

== Client Setup (RHEL-8) ==

1) Register the client host to the satellite server and attach the "Test" Content view on it.
2) Install podman on the RHEL 8 client host and Login to "registry.redhat.io".
# dnf install podman -y
# podman login registry.redhat.io

3) Pull the images from the registry hub.
# podman pull registry.redhat.io/ubi8/ubi-minimal

4) From there on, to reproduce the issue, install execute the following command:
# podman run --rm -it registry.redhat.io/ubi8/ubi-minimal  microdnf --enablerepo=RedHat_Custom_Hashicorp install -y terraform
