sed -i 's/#precedence ::ffff:0:0\/96  100/precedence ::ffff:0:0\/96  100/' /etc/gai.conf

[FIXED] Repository ‘http://security.debian.org/debian-security buster/updates InRelease’ changed its ‘Suite’ value from ‘stable’ to ‘oldstable’
运行一次下面代码就好了

apt-get update --allow-releaseinfo-change

首先设置hostname，根据实际情况自行修改，我这里设置为freenn

hostnamectl set-hostname freenn

修改/etc/hosts，添加如下内容

127.0.0.1 localhost.localdomain localhost
8.8.8.8 freenn.proxmox.com freenn

8.8.8.8为你服务器公网IP，请自行修改
如果你的hostname设置为freenn，那么必须设置域名为freenn.proxmox.com，同理如果hostname设置为test，则域名为test.proxmox.com

如果是安装pve8,且版本为bookworm，则添加如下源

echo "deb https://mirrors.apqa.cn/proxmox/debian/pve bookworm port">/etc/apt/sources.list.d/pveport.list

如果是安装pve7,且系统版本为debian11，则添加如下源

echo "deb https://mirrors.apqa.cn/proxmox/debian/pve bullseye port">/etc/apt/sources.list.d/pveport.list

添加apt-key

curl https://mirrors.apqa.cn/proxmox/debian/pveport.gpg -o /etc/apt/trusted.gpg.d/pveport.gpg

安装Proxmox VE
使用正确的path

export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

安装Proxmox VE

apt update && apt install -y proxmox-ve

apk add zerotier-one
/etc/init.d/zerotier-one -d
zerotier-one -d  
rc-update add zerotier-one sysinit

最后加入网络 zerotier-cli join

编辑 /etc/pve/nodes/freenn/lxc 路径里的conf文件，在文件最下方添加代码
PVE5开TUN代码

lxc.cgroup.devices.allow: c 10:200 rwm
lxc.mount.entry: /dev/net dev/net none bind,create=dir

PVE6.4开TUN代码

lxc.cgroup.devices.allow: c 10:200 rwm
lxc.hook.autodev = sh -c "modprobe tun; cd ${LXC_ROOTFS_MOUNT}/dev; mkdir net; mknod net/tun c 10 200; chmod 0666 net/tun"

PVE7.4开TUN代码

lxc.apparmor.profile: unconfined
lxc.cgroup.devices.allow: a
lxc.cap.drop: 
lxc.cgroup2.devices.allow: c 10:200 rwm
lxc.mount.entry: /dev/net/tun dev/net/tun none bind,create=file
