参考官网说明：https://pve.proxmox.com/wiki/Package_Repositories，把pve的源换成pve-no-subscription类型的。

• 修改/etc/apt/sources.list.d/pve-enterprise.list

#deb https://enterprise.proxmox.com/debian/pve bookworm pve-enterprise
deb http://download.proxmox.com/debian/pve bookworm pve-no-subscription

• 修改/etc/apt/sources.list.d/ceph.list

#deb https://enterprise.proxmox.com/debian/ceph-quincy bookworm enterprise
deb http://download.proxmox.com/debian/ceph-reef bookworm no-subscription
