在 Ubuntu 20.04.3 上运行 ufw 时出现问题

我是 Ubuntu 新手，为了尝试它，我从 Microsoft 商店安装了 Ubuntu 应用程序并在我的 Windows 10 笔记本电脑上运行它，我尝试启用 UFW，但出现了以下问题：

:~$ sudo ufw enable

ERROR: problem running ufw-init

Problem loading ipv6 (skipping)
Problem running '/etc/ufw/before.rules'
Problem running '/etc/ufw/after.rules'
Problem running '/etc/ufw/user.rules'

因为我对此很陌生，我对 iptables、过滤器和初始化一无所知，或者只是因为它在我的 Windows 笔记本电脑上。我已经使用以下软件更新和升级了所有内容；

sudo apt-get update  
sudo apt-get upgrade

并在 root 状态下尝试了该命令，但没有成功。如果您需要任何信息，我很乐意提供给您。提前致谢。

只需下载最新的 Ubuntu 版本（https://ubuntu.com/download/desktop) 并将其安装在可启动的 U 盘或 USB 上。只需使用此 U 盘启动，然后选择“试用”或“安装”。按照说明操作。通过“试用”，您可以了解是否需要此系统。如果是，您可以使用相同的安装 U 盘在双启动中安装它。做出选择。但在安装之前，请在硬盘上创建单独的分区。
