无法启用 UFW 防火墙

我正在尝试在我的 ubuntu 22.04 上设置代码服务器。但是我意识到我的防火墙未启用，并尝试使用另一个线程中的说明启用它：https://superuser.com/questions/590600/ufw-is-active-but-not-enabled-why。

当检查防火墙的状态时，我被告知它处于非活动状态。当执行 sudo ufw enable 时，我收到此错误消息。：

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/ufw/util.py", line 427, in under_ssh
    ppid = get_ppid(pid)
  File "/usr/lib/python3/dist-packages/ufw/util.py", line 419, in get_ppid
    ppid = open(name).readlines()[0].split(')')[1].split()[1]
IndexError: list index out of range

在处理上述异常的过程中，又发生了另一个异常：

Traceback (most recent call last):
  File "/usr/sbin/ufw", line 138, in <module>
    not ui.continue_under_ssh():
  File "/usr/lib/python3/dist-packages/ufw/frontend.py", line 901, in continue_under_ssh
