自用是一台i3-5010U的小主机，安装PVE6.3出现白屏

白屏时现象:有鼠标，鼠标右键有弹出菜单，折腾过如下方法，来自网上各个帖子与尝试，均失败

先用的HDMI，失败

从bios中，将Graphic设定为LVDS，甭管是最高分辨率还是最低分辨率，直接不亮了，失败中的失败，都要重新给bios放电重置

换国内源 更新vpe5.4

echo "deb https://mirrors.ustc.edu.cn/debian/ stretch main contrib non-free deb-src https://mirrors.ustc.edu.cn/debian/ stretch main contrib non-free deb https://mirrors.ustc.edu.cn/debian/ stretch-updates main contrib non-free deb-src https://mirrors.ustc.edu.cn/debian/ stretch-updates main contrib non-free deb https://mirrors.ustc.edu.cn/debian/ stretch-backports main contrib non-free deb-src https://mirrors.ustc.edu.cn/debian/ stretch-backports main contrib non-free deb https://mirrors.ustc.edu.cn/debian-security/ stretch/updates main contrib non-free deb-src https://mirrors.ustc.edu.cn/debian-security/ stretch/updates main contrib non-free" > /etc/apt/sources.list

或者换 163的源

cat > /etc/apt/sources.list <<EOF
deb http://mirrors.163.com/debian/ buster main non-free contrib
deb http://mirrors.163.com/debian/ buster-updates main non-free contrib
deb http://mirrors.163.com/debian/ buster-backports main non-free contrib
deb-src http://mirrors.163.com/debian/ buster main non-free contrib
deb-src http://mirrors.163.com/debian/ buster-updates main non-free contrib
deb-src http://mirrors.163.com/debian/ buster-backports main non-free contrib
deb http://mirrors.163.com/debian-security/ buster/updates main non-free contrib
deb-src http://mirrors.163.com/debian-security/ buster/updates main non-free contrib
EOF

修改pve 5.x 更新源地址为 no subscription，不使用企业更新源

echo "deb http://mirrors.ustc.edu.cn/proxmox/debian/pve/ stretch pve-no-subscription" > /etc/apt/sources.list.d/pve-no-sub.list

关闭pve 5.x企业更新源

sed -i.bak 's|deb https://enterprise.proxmox.com/debian stretch pve-enterprise|# deb https://enterprise.proxmox.com/debian stretch pve-enterprise|' /etc/apt/sources.list.d/pve-enterprise.list

修改 ceph镜像更新源

echo "deb http://mirrors.ustc.edu.cn/proxmox/debian/ceph-luminous stretch main" >> /etc/apt/sources.list.d/ceph.list

开始更新即可

apt update && apt dist-upgrade

升级Corosync到Corosync 3

关闭高可用服务，只有一台pve的可以忽略。

systemctl stop pve-ha-lrm
systemctl stop pve-ha-crm

添加Proxmox Corosync 3 Stretch存储库

echo“deb http://mirrors.ustc.edu.cn/proxmox/debian/corosync-3/ stretch main”> /etc/apt/sources.list.d/corosync3.list

运行命令更新

apt update

根据官方手册支持执行：

apt list --upgradeable
apt dist-upgrade --download-only
apt dist-upgrade

如果关闭了高可用服务的在更新完毕后需要重新启动高可用服务

systemctl start pve-ha-lrm
systemctl start pve-ha-crm

升级pve到6.3
执行以下更新命令确保最新：

apt update
apt dist-upgrade

执行镜像源更新命令，将Debian的镜像源更换为升级源

sed -i 's/stretch/buster/g' /etc/apt/sources.list

添加Proxmox VE 6的镜像存储库地址

echo "deb http://mirrors.ustc.edu.cn/proxmox/debian/pve buster pve-no-subscription " > /etc/apt/sources.list.d/pve-no-sub.list

修改其他镜像源的升级包地址

sed -i -e 's/stretch/buster/g' /etc/apt/sources.list.d/pve-install-repo.list

修改Ceph的升级包地址

echo "deb http://mirrors.ustc.edu.cn/proxmox/debian/ceph-luminous buster main" > /etc/apt/sources.list.d/ceph.list

开始运行更新命令

apt update
apt dist-upgrade

在更新的过程中会出现几次输入的交互，第一次提示apt相关信息，输入Q退出继续执行更新，后续直接确认回车即可。
