ubuntu - 未满足的依赖项 - 无法安装 python-catkin-pkg

Question

我正在尝试安装roslaunch但它说我需要安装roslib，然后说我需要安装catkin，它说我需要安装python-catkin-pkg。

我先调用source /opt/ros/kinetic/setup.bash对于我尝试安装的每个依赖项。当它到达 sudo apt-get install python-catkin-pkg它说 python-catkin-pkg 已经是最新版本(0.4.16-000)

于是我尝试用 sudo apt-get install catkin 安装 catkin终端返回消息: >Reading package lists... Done
