在这里我想安装 plank (ppa:docky-core/stable)，但是当我尝试
sudo apt-get install plank
它不起作用，我也尝试安装另一个应用程序，但仍然不起作用，并显示此消息。我也尝试了这个命令
sudo rm /var/lib/apt/lists/* -vf，但仍然不起作用
以下是消息：
这是输出来源列表：

有人能帮帮我吗？

好的，我明白了。您的 Visual Studio Code（终端名称为）出现故障，code导致其他软件包无法安装。因此请执行以下步骤：
sudo dpkg --remove --force-all code
如果失败：
sudo rm -i /var/lib/dpkg/info/code.*
sudo dpkg --remove --force-remove-reinstreq code
确认 Apt 已修复。以下命令不应返回任何错误：
sudo apt-get update
致谢这里。
