最近尝试用Proxmox 7.2 安装CEPH娱乐，Proxmox 7.2 默认来自官方的源，国内慢的一逼高峰期只有个几KB的速度，所以换源。
Debian系统源(阿里云源)和中科大proxmox源。
Debian和 Ubuntu 体系比较少玩，操作起来好生疏。
一、更换阿里云的源
vi /etc/apt/sources.list
替换为：
deb http://mirrors.aliyun.com/debian/ bullseye main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ bullseye main non-free contrib
deb http://mirrors.aliyun.com/debian-security/ bullseye-security main
deb-src http://mirrors.aliyun.com/debian-security/ bullseye-security main
deb http://mirrors.aliyun.com/debian/ bullseye-updates main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ bullseye-updates main non-free contrib
deb http://mirrors.aliyun.com/debian/ bullseye-backports main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ bullseye-backports main non-free contrib
二、去除企业版源
vi /etc/apt/sources.list.d/pve-enterprise.list
注释掉，如：
## deb https://enterprise.proxmox.com/debian/pve buster pve-enterprise
三、修改自带的CEPH源
vi /etc/apt/sources.list.d/ceph.list
替换为
#deb http://download.proxmox.com/debian/ceph-nautilus buster main
deb http://mirrors.ustc.edu.cn/proxmox/debian/ceph-nautilus buster main
四、更新
apt update
完事，然后一键安装。
