This error is caused by not having an enterprise Proxmox subscription/license. However, Proxmox can use Free/Testing/Non-Enterprise packages for Ceph.
For older versions of Proxmox like 7.1
This is normally caused by the fact that you don't have an Enterprise Subscription, either update your subscription or comment the Enterprise repo out in /etc/apt/sources.list.d/pve-enterprise.list
Alternatively you can simply just delete /etc/apt/sources.list.d/pve-enterprise.list and you'll be ok.
Here is how /etc/apt/sources.list should look (assuming you are using Bullseye):
deb http://ftp.ca.debian.org/debian bullseye main contrib
deb http://ftp.ca.debian.org/debian bullseye-updates main contrib
# security updates
deb http://security.debian.org bullseye-security main contrib
Here is how /etc/apt/sources.list.d/ceph.list should look:
deb http://download.proxmox.com/debian/ceph-pacific bullseye main
For newer versions of Proxmox (eg. 8+)
You may also need to enable the no-subscription repo:
https://pve.proxmox.com/wiki/Package_Repositories#sysadmin_enterprise_repo
sources.list for version 8 of Proxmox with no-subscription repo:
deb http://ftp.debian.org/debian bookworm main contrib
deb http://ftp.debian.org/debian bookworm-updates main contrib
# Proxmox VE pve-no-subscription repository provided by proxmox.com,
# NOT recommended for production use
deb http://download.proxmox.com/debian/pve bookworm pve-no-subscription
# security updates
deb http://security.debian.org/debian-security bookworm-security main contrib
Also edit /etc/apt/sources.list.d/ceph.list
deb http://download.proxmox.com/debian/ceph-reef bookworm no-subscription
