Answer 1

我是 Gufw 开发人员。

由于 Wayland，您无法运行任何根用户界面（Gparted、Synaptic、Gufw...）。

相关bug：https : //bugs.launchpad.net/ubuntu/+source/gui-ufw/+bug/1713238

这里的所有信息：https : //bugs.launchpad.net/ubuntu/+source/backintime/+bug/1713313/comments/44

正如您在该链接中所读到的那样，恐怕它不会修复，因为它已关闭，无法修复：/

一个拥抱，我很抱歉。

一个肮脏的解决方法，但这是使 gufw 使用 Wayland 在 Ubuntu 17.10 上工作的一种方法：

• 创建文件~/bin/gufw并为其提供以下内容：

  #!/bin/sh
  xhost SI:localuser:root
  /usr/bin/gufw
  xhost -SI:localuser:root
  

• 使文件可执行：

  chmod +x ~/bin/gufw
  

编辑：

更一步一步的解释是：

• 按Ctrl+ Alt+T打开一个终端窗口。

• 运行命令：

  mkdir -p bin
  

  （即输入并按Enter）

• 使用以下命令打开gedit文本编辑器：

  gedit bin/gufw
  

• 复制上面的内容并将其粘贴到gedit窗口中。

• 保存并退出gedit。

• 运行命令：

  chmod +x bin/gufw
  

• 通过运行以下命令退出终端窗口：

  exit
