PVE 从 7.4 升级到 8.0

PVE8.0 正式版官方已出，何先生作为追新一族，是必须要跟的，粗略看了下官网的升级方法，成功搞定。

第一步：

备份所有虚拟机和配置，以防万一数据丢失。

第二步：

删掉其他无关的源

rm /etc/apt/sources.list.d/*

第三步：

替换 deban12 和 pve8 的无订阅源

nano /etc/apt/sources.list

源 1：中科大的
deb https://mirrors.ustc.edu.cn/debian bookworm main contrib  non-free non-free-firmware
deb https://mirrors.ustc.edu.cn/debian-security/ bookworm-security main contrib non-free non-free-firmware
deb https://mirrors.ustc.edu.cn/debian bookworm-updates main contrib non-free non-free-firmware
deb https://mirrors.ustc.edu.cn/debian bookworm-backports main contrib non-free non-free-firmware
deb https://mirrors.ustc.edu.cn/proxmox/debian/pve bookworm pve-no-subscription

源 2：清华大学的(未测试）
deb https://mirrors.tuna.tsinghua.edu.cn/debian bookworm main contrib  non-free non-free-firmware
deb https://mirrors.tuna.tsinghua.edu.cn/debian-security/ bookworm-security main contrib non-free non-free-firmware

deb https://mirrors.tuna.tsinghua.edu.cn/debian bookworm-backports main contrib non-free non-free-firmware
deb https://mirrors.tuna.tsinghua.edu.cn/proxmox/debian/pve bookworm pve-no-subscription

源 3：官方源
deb http://deb.debian.org/debian bookworm main contrib non-free 
deb http://deb.debian.org/debian-security/ bookworm-security main contrib non-free
deb http://deb.debian.org/debian bookworm-updates main contrib non-free
deb http://deb.debian.org/debian bookworm-backports main contrib non-free
deb http://download.proxmox.com/debian/pve  bookworm pve-no-subscription

第四步：

何先生升级过程中有一些小问题，提示：you are attempting to remove the meta-package ‘proxmox-ve’

后面经过测试，需要添加一个源，这个源可能需要魔法访问。

nano /etc/apt/sources.list.d/ceph.list
deb http://download.proxmox.com/debian/ceph-quincy bookworm main

开始升级，保持 pve 网络畅通

apt update
apt dist-upgrade

期间可能会有提示，按 Y 回车或者 ok 就行
