无法修正错误，因为您要求某些软件包保持现状，就是它们破坏了软件包间的依赖关系

[850874743]

ubuntu20.04安装foxy的ros2失败，尝试了几次了，都是一样的错误，下边是失败的提示：
Run CMD Task:[sudo apt install ros-foxy-desktop -y]
正在读取软件包列表... 完成
正在分析软件包的依赖关系树
正在读取状态信息... 完成
有一些软件包无法被安装。如果您用的是 unstable 发行版，这也许是
因为系统无法达到您要求的状态造成的。该版本中可能会有一些您需要的软件
包尚未被创建或是它们已被从新到(Incoming)目录移出。
下列信息可能会对解决问题有所帮助：

下列软件包有未满足的依赖关系：
ros-foxy-desktop : 依赖: ros-foxy-depthimage-to-laserscan 但是它将不会被安装
依赖: ros-foxy-image-tools 但是它将不会被安装
依赖: ros-foxy-intra-process-demo 但是它将不会被安装
依赖: ros-foxy-pcl-conversions 但是它将不会被安装
依赖: ros-foxy-rqt-common-plugins 但是它将不会被安装
依赖: ros-foxy-rviz-default-plugins 但是它将不会被安装
依赖: ros-foxy-rviz2 但是它将不会被安装
E: 无法修正错误，因为您要求某些软件包保持现状，就是它们破坏了软件包间的依赖关系。
Run CMD Task:[sudo apt install ros-foxy-desktop -y]
[-]Result:code:100 是它将不会被安装 它将不会被安装 装

============================================================
请注意我，检测你在安装过程中出现依赖问题，请在稍后输入n,再选择y,即可解决（若无法解决，清在稍后手动运行命令: sudo aptitude install ros-foxy-desktop)

然后我按照操作，先n然后y
下列动作将解决这些依赖关系：
