已遵循http：//wiki.ros.org/kinetic/Installat中列出的步骤序列. (尝试在Ubuntu 16.04中安装ROS kinetic)输入以下命令时出错：

$sudo apt-get install ros-kinetic-desktop-full

我有同样的问题因为我在ROS之前安装了Gazebo.

如果你做了同样的事情,那么你可能会遇到这个错误.

您只需卸载Gazebo及其依赖项,然后尝试安装完整版本的ROS. Gazebo通常包含在ROS的完整版本中.如果它没有包含在您的版本中,那么在安装ROS之后,您可以安装Gazebo.

删除凉亭：

sudo apt-get remove gazebo9

“gazebo9”必须替换为您的Gazebo版本.

然后删除其依赖项

sudo apt-get autoremove

此命令将删除所有不必要的依赖项.之后,使用官方文档安装ROS.希望这会帮助你.

Note: ROS full versions comes with Gazebo
