已经解决。
重试安装时，注意到有个提示，按照提示执行后安装成功。虽然最后启动又有新问题，但都能百度到。小鱼牛逼，还是很方便的。

你好，你是遇到下边这种错误吗：
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
