[ovirt-users] unable to upgrade engine to 4.4.10 from 4.4.8

I am unable to upgrade my hosted engine from version 4.4.8 to 4.4.10. I suspect the problem is because of the obsolescence of CentOS Linux 8. DNF gives me the following error: CentOS Linux 8 - AppStream Error: Failed to download metadata for repo 'appstream': Cannot prepare internal mirrorlist: No URLs in mirrorlist This is the list of repositories on my engine: appstream CentOS Linux 8 - AppStream baseos CentOS Linux 8 - BaseOS extras CentOS Linux 8 - Extras ovirt-4.4 Latest oVirt 4.4 Release ovirt-4.4-advanced-virtualization Advanced Virtualization packages for x86_64 ovirt-4.4-centos-ceph-pacific Ceph packages for x86_64 ovirt-4.4-centos-gluster8 CentOS-8 - Gluster 8 ovirt-4.4-centos-nfv-openvswitch CentOS-8 - NFV OpenvSwitch ovirt-4.4-centos-opstools CentOS-8 - OpsTools - collectd ovirt-4.4-centos-ovirt44 CentOS-8 - oVirt 4.4 ovirt-4.4-copr:copr.fedorainfracloud.org:sac:gluster-ansible Copr repo for gluster-ansible owned by sac ovirt-4.4-copr:copr.fedorainfracloud.org:sbonazzo:EL8_collection Copr repo for EL8_collection owned by sbonazzo ovirt-4.4-epel Extra Packages for Enterprise Linux 8 - x86_64 ovirt-4.4-openstack-victoria OpenStack Victoria Repository ovirt-4.4-virtio-win-latest virtio-win builds roughly matching what will be shipped in upcoming RHEL powertools CentOS Linux 8 - PowerTools Your guidance on how to proceed is much appreciated.
