一、Debian系统源(PVE5-Debain9 )
nano /etc/apt/sources.list
#deb http://ftp.debian.org/debian stretch main contrib
deb http://mirrors.163.com/debian stretch main contrib
#deb http://ftp.debian.org/debian stretch-updates main contrib
deb http://mirrors.163.com/debian stretch-updates main contrib
# security updates
#deb http://security.debian.org stretch/updates main contrib
deb http://mirrors.163.com/debian-security stretch/updates main contrib二、Proxmox源(PVE5-Debain9)
nano /etc/apt/sources.list.d/pve-enterprise.list
#deb https://enterprise.proxmox.com/debian/pve stretch pve-enterprise
#deb http://download.proxmox.com/debian/pve stretch pve-no-subscription
deb http://mirrors.ustc.edu.cn/proxmox/debian/pve stretch pve-no-subscription三、 Ceph源(PVE5-Debain9)
nano /etc/apt/sources.list.d/ceph.list
#deb http://download.proxmox.com/debian/ceph-luminous stretch main
deb http://mirrors.ustc.edu.cn/proxmox/debian/ceph-luminous stretch main四、Debian系统源(PVE6-Debain10)
nano /etc/apt/sources.list
#deb http://deb.debian.org/debian buster main contrib
deb http://mirrors.163.com/debian buster main contrib
#deb http://deb.debian.org/debian buster-updates main contrib

nano /etc/apt/sources.list.d/pve-enterprise.list
#deb https://enterprise.proxmox.com/debian/pve buster pve-enterprise
#deb http://download.proxmox.com/debian/pve buster pve-no-subscription
deb http://mirrors.ustc.edu.cn/proxmox/debian/pve buster pve-no-subscription六、 Ceph源(PVE6-Debain10)
nano /etc/apt/sources.list.d/ceph.list
#deb http://download.proxmox.com/debian/ceph-nautilus buster main
deb http://mirrors.ustc.edu.cn/proxmox/debian/ceph-nautilus buster main七、一次性配置PVE6源 （Proxmox6+Debain10+Ceph14）
删除原有的源：
rm /etc/apt/sources.list.d/pve-enterprise.list
rm/etc/apt/sources.list.d/ceph.list添加新的源：
nano /etc/apt/sources.list
#deb http://ftp.debian.org/debian buster main contrib
#deb http://ftp.debian.org/debian buster-updates main contrib
# security updates
#deb http://security.debian.org buster/updates main contrib
# debian aliyun source
deb https://mirrors.aliyun.com/debian buster main contrib non-free
deb https://mirrors.aliyun.com/debian buster-updates main contrib non-free
deb https://mirrors.aliyun.com/debian-security buster/updates main contrib non-free
# proxmox source
# deb http://download.proxmox.com/debian/pve buster pve-no-subscription
deb http://mirrors.ustc.edu.cn/proxmox/debian/pve buster pve-no-subscription
# ceph source
#deb http://download.proxmox.com/debian/ceph-nautilus buster main
deb http://mirrors.ustc.edu.cn/proxmox/debian/ceph-nautilus buster main说明：CEPH.LIST 总是恢复的问题
经过测试，在PVE6按四、五、六配置完后，每次apt-get update时，就会把Ceph.list源恢复。因此建议使用采用第七步方案。
