wg-quick：未找到公共接口

我正在尝试在远程 Ubuntu 22.04 服务器上配置 WireGuard，并在服务器上执行以下命令

sudo apt install wireguard

在服务器上创建私钥和公钥

wg genkey | tee privatekey | wg pubkey > publickey

创建配置文件 /etc/wireguard/wg0.conf

[Interface]
PrivateKey=+******n1+uTWXU=
Address=10.0.0.1/8
SaveConfig=true
PostUp = iptables -A FORWARD -i wg0 -j ACCEPT; iptables -t nat -A POSTROUTING -o <public-interface> -j MASQUERADE;
PostDown = iptables -D FORWARD -i wg0 -j ACCEPT; iptables -t nat -D POSTROUTING -o <public-interface> -j MASQUERADE;::
ListenPort = somePort

当我使用以下命令启用 wg0 接口时

wg-quick up wg0

它说“公共接口：没有这样的文件或目录”

root@srv173:~# wg-quick up wg0
[#] ip link add wg0 type wireguard
[#] wg setconf wg0 /dev/fd/63
[#] ip -4 address add 10.0.0.1/8 dev wg0
[#] ip link set mtu 1420 up dev wg0
[#] iptables -A FORWARD -i wg0 -j ACCEPT; iptables -t nat -A POSTROUTING -o <public-interface> -j MASQUERADE;
/usr/bin/wg-quick: line 295: public-interface: No such file or directory
[#] ip link delete dev wg0
root@srv173:~#

我的配置有什么问题？
