Proxmox VE without a subscription: no-subscription repositories on PVE 9 (deb822) and PVE 8

PVE 9 uses .sources (deb822) on trixie; PVE 8 uses .list on bookworm. Enterprise to Enabled: false, no-subscription on, same trick for Ceph and PBS. Copy/paste for both versions.

Proxmox: /usr/share/proxmox-ve/pve-apt-hook: not found when updating

The snippet /etc/apt/apt.conf.d/10pveapthook calls a script that no longer exists because proxmox-ve went away. Empty stub, apt install -f, apt install proxmox-ve. If you removed Proxmox on purpose, delete the snippet.
