Configuring OMV5 on RPi 4. Error on Update Management -> Check Updates

Hello,
This is my first time trying to get OMV5 installed on an Pi 4. I followed Techno Dad Life's video for installation. When i tried to Check for updates in Update Management I get the following error

Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; apt-get update 2>&1' with exit code '100': Get:1 file:/var/cache/openmediavault/archives InRelease Ign:1 file:/var/cache/openmediavault/archives InRelease Get:2 file:/var/cache/openmediavault/archives Release Ign:2 file:/var/cache/openmediavault/archives Release Get:3 file:/var/cache/openmediavault/archives Packages Ign:3 file:/var/cache/openmediavault/archives Packages Get:4 file:/var/cache/openmediavault/archives Translation-en Ign:4 file:/var/cache/openmediavault/archives Translation-en Get:3 file:/var/cache/openmediavault/archives Packages Ign:3 file:/var/cache/openmediavault/archives Packages Get:4 file:/var/cache/openmediavault/archives Translation-en Ign:4 file:/var/cache/openmediavault/archives Translation-en Get:3 file:/var/cache/openmediavault/archives Packages Ign:3 file:/var/cache/openmediavault/archives Packages Get:4 file:/var/cache/openmediavault/archives Translation-en Ign:4 file:/var/cache/openmediavault/archives Translation-en Get:3 file:/var/cache/openmediavault/archives Packages Ign:3 file:/var/cache/openmediavault/archives Packages Get:4 file:/var/cache/openmediavault/archives Translation-en Ign:4 file:/var/cache/openmediavault/archives Translation-en Get:3 file:/var/cache/openmediavault/archives Packages Ign:3 file:/var/cache/openmediavault/archives Packages Get:4 file:/var/cache/openmediavault/archives Translation-en Ign:4 file:/var/cache/openmediavault/archives Translation-en Get:3 file:/var/cache/openmediavault/archives Packages Ign:3 file:/var/cache/openmediavault/archives Packages Get:4 file:/var/cache/openmediavault/archives Translation-en Ign:4 file:/var/cache/openmediavault/archives Translation-en Get:3 file:/var/cache/openmediavault/archives Packages Get:4 file:/var/cache/openmediavault/archives Translation-en Ign:4 file:/var/cache/openmediavault/archives Translation-en Get:5 http://security.debian.org/debian-security buster/updates InRelease [39.1 kB] Hit:6 https://openmediavault.github.io/packages usul InRelease Hit:7 http://raspbian.raspberrypi.org/raspbian buster InRelease Hit:8 http://archive.raspberrypi.org/debian buster InRelease Err:5 http://security.debian.org/debian-security buster/updates InRelease The following signatures couldn't be verified because the public key is not available: NO_PUBKEY AA8E81B4331F7F50 NO_PUBKEY 112695A0E562B32A Get:9 http://cdn-fastly.deb.debian.org/debian buster-backports InRelease [46.7 kB] Hit:10 http://packages.openmediavault.org/public usul InRelease Hit:11 http://packages.openmediavault.org/public usul-proposed InRelease Err:9 http://cdn-fastly.deb.debian.org/debian buster-backports InRelease The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 04EE7237B7D453EC NO_PUBKEY 648ACFD622F3D138 Reading package lists...

Any help is appreciated. Thanks

I had installed the Raspbian Buster Desktop version. I will try with Lite.

That worked!!! Thank you.
