you can't use the enterprise repository without setting it up. take a look here for more information [0]

you either need to set it up, or you need to use pve-no-subscription

you have wrong sources.lists. check the upgrade doc again.
thanks all for the help.

I managed to solve my issue and upgraded from 5.4 to 6.0 successfully now.

I moved pve-enterprise.list and pve-no-subscription.list to /home from /etc/apt/sources.list.d/

Copy this below into File : /etc/apt/sources.list

deb http://ftp.debian.org/debian buster main contrib
deb http://ftp.debian.org/debian buster-updates main contrib

# PVE pve-no-subscription repository provided by proxmox.com,
# NOT recommended for production use
deb http://download.proxmox.com/debian/pve buster pve-no-subscription

# security updates
deb http://security.debian.org buster/updates main contrib
