pve7升级pve8

步骤1： 升级pve7到最新版本

备份好原始源数据

pve7的清华源-/etc/apt/sources.list

# 7.x

deb https://mirrors.tuna.tsinghua.edu.cn/debian bullseye main contrib non-free
deb https://mirrors.tuna.tsinghua.edu.cn/debian bullseye-updates main contrib non-free
deb https://mirrors.tuna.tsinghua.edu.cn/debian bullseye-backports main contrib non-free

# security updates
deb https://mirrors.tuna.tsinghua.edu.cn/debian-security bullseye-security main contrib non-free

pve7的清华企业源-/etc/apt/sources.list.d/pve-enterprise.list

deb https://mirrors.tuna.tsinghua.edu.cn/proxmox/debian bullseye pve-no-subscription

apt update && apt upgrade -y

步骤2：修改源为pve8同时删除pve7的源

pve8的清华源

# 8.0
deb https://mirrors.tuna.tsinghua.edu.cn/debian bookworm main contrib non-free non-free-firmware
deb https://mirrors.tuna.tsinghua.edu.cn/debian bookworm-updates main contrib non-free non-free-firmware
deb https://mirrors.tuna.tsinghua.edu.cn/debian bookworm-backports main contrib non-free non-free-firmware

# security updates
#deb https://mirrors.tuna.tsinghua.edu.cn/debian-security bookworm-security main contrib non-free non-free-firmware
deb https://security.debian.org/debian-security bookworm-security main contrib non-free non-free-firmware

保留官方的加密源，防止清华源抽风

pve8的清华企业源

deb https://mirrors.tuna.tsinghua.edu.cn/proxmox/debian/pve bookworm pve-no-subscription

apt update

步骤3：添加ceph.list，防止出现404报错

echo "deb http://download.proxmox.com/debian/ceph-quincy bookworm no-subscription" > /etc/apt/sources.list.d/ceph.list

步骤4：下载密钥

wget https://enterprise.proxmox.com/debian/proxmox-release-bookworm.gpg -O /etc/apt/trusted.gpg.d/proxmox-release-bookworm.gpg

步骤5：检查升级

pve7to8 --full

步骤6：没有错误之后，升级

apt update

apt dist-upgrade

可能会出现需要--fix-missing的情况，修复之后继续

apt-get update --fix-missing

没有特殊需求就一路回车

步骤7：升级完成重启，然后检查升级结果

systemctl reboot
