答案1

我是一名 Gufw 开发人员。

由于 Wayland，您无法运行任何根 UI（Gparted、Synaptic、Gufw……）。

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

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

正如你在那个链接中看到的，我担心它不会被修复，因为它被关闭了无法修复：/

https://bugzilla.redhat.com/show_bug.cgi?id=1274451

拥抱一下，我很抱歉。

这是一个肮脏的解决方法，但这是让 gufw 在 Ubuntu 17.10 上使用 Wayland 工作的一种方法：

  • 创建文件~/bin/gufw并赋予其以下内容：

    #!/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++打开终端窗口Alt。T

  • 运行命令：

    mkdir -p bin

    （即输入并按Enter）

  • 打开编辑使用以下命令编辑文本：

    gedit bin/gufw

  • 复制上述内容并粘贴到编辑窗户。

  • 保存并退出编辑。

  • 运行命令：

    chmod +x bin/gufw

  • 通过运行以下命令退出终端窗口：

    exit

答案3

无需重新安装；

经过快速搜索，我发现 Gufw 缺少 python 依赖项。看来需要添加 python-gi 包作为依赖项。

修复步骤：

  1. sudo apt 安装 python-gi
  2. 海湾战争
  3. 输入密码

答案4

xhost si:localuser:root

pip3 install ufw
sudo apt-get install python-gobject
sudo apt-get install --reinstall gufw
sudo gufw

在 Ubuntu 18.04 上对我有用！我遇到了同样的问题！我希望我没有忘记任何 cmd，因为我尝试了很多东西……
