title: Oracle8 ULN 'dnf check-update' differs from 'dnf update'
body: <p>I recently migrated a RedHat 8 system to Oracle Linux ULN and I'm seeing a discrepancy between &quot;dnf update&quot; and &quot;dnf check-update&quot; (see output below). The listed Perl modules are installed but the .noarch version which I would prefer to retain. Is there a reason why &quot;dnf check-update&quot; would show these modules?</p>
