Trying to install proxmox-ve throws the following

root@pve:~# apt install proxmox-ve
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Package proxmox-ve is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  pve-kernel-helper proxmox-kernel-helper

E: Package 'proxmox-ve' has no installation candidate

What's causing all this?!

You have the Debian and Ceph repositorie but are missing deb http://download.proxmox.com/debian/pve bookworm pve-no-subscription

EDIT: Maybe double check the step 'Add the Proxmox VE 8 Package Repository' from the guide: https://pve.proxmox.com/wiki/Upgrade_from_7_to_8 ?

Thanks, I double checked and yes was missing that one repository because I didn't click through to see the no-subscription list.
That was added, i then did an apt update followed by an apt dist-upgrade with the following result
