Proxmox Initial Setup
Disable enterprise and enable no-subscription repo
**As of Proxmox 8, this can all be done through the GUI as well by clicking on a node and going to updates –> repositories
Disable the enterprise repo:
1nano /etc/apt/sources.list.d/pve-enterprise.listThere should be one line in this file. Comment it out: `
1# deb https://enterprise.proxmox.com/debian/pve bookworm pve-enterpriseAdd the pve-no-subscription repo to the file /etc/apt/sources.list
1deb http://ftp.debian.org/debian bookworm main contrib
