proxmox从6.0升级到6.3
1.删除企业源
rm -rf /etc/apt/sources.list.d/pve-enterprise.list
2.下载秘钥
wget http://mirrors.ustc.edu.cn/Proxmox/debian/proxmox-ve-release-6.x.gpg -O /etc/apt/trusted.gpg.d/proxmox-ve-release-6.x.gpg
3.添加国内源
echo "deb http://mirrors.ustc.edu.cn/proxmox/debian/pve buster pve-no-subscription" >/etc/apt/sources.list.d/pve-install-repo.list
注意！！！注意！！！！
deb http://mirrors.ustc.edu.cn/proxmox/debian/pve strech pve-no-subscription
strech注意修改，否则造成无法升级为pve6.3
strech–debian 9–pve 5.x
buster–debian 10–pve 6.x
4.配置国内debian源
echo "deb http://mirrors.ustc.edu.cn/debian buster main contrib deb http://mirrors.ustc.edu.cn/debian buster-updates main contrib deb http://mirrors.ustc.edu.cn/debian-security buster/updates main contrib" > /etc/apt/sources.list
5.pve_ceph设置国内源
