Ubuntu 16.04 安装ROS kinetic提示Depends: ros

今天在Ubuntu 16.04 安装ROS kinetic，按照官网流程在一步步走：

一.设置安装源

sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'
1

二.设置keys

sudo apt-key adv --keyserver hkp://ha.pool.sks-keyservers.net:80 --recv-key 0xB01FA116
1

三.更新系统安装

apt-get updateapt-get install ros-kinetic-desktop-full

然后就在这一步，报错信息如下：

Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation:The following packages have unmet dependencies: ros-kinetic-desktop-full : Depends: ros-kinetic-desktop but it is not going to be installed Depends: ros-kinetic-perception but it is not going to be installed Depends: ros-kinetic-simulators but it is not going to be installed Depends: ros-kinetic-urdf-tutorial but it is not going to be installed E: Unable to correct problems, you have held broken packages.

百思不得其解，在网上没搜到答案，不过看他们的截图，貌似都把Ubuntu源设置成了中科大源，解决方法也正好在这里！

解决：

1.删除ros-latest.list

rm -rf /etc/apt/sources.list.d/ros-latest.list
1

2.修改源：

vi /etc/apt/sources.list
1

然后改为以下内容：

deb http://mirrors.ustc.edu.cn/ubuntu/ xenial main restricted universe multiversedeb http://mirrors.ustc.edu.cn/ubuntu/ xenial-security main restricted universe multiversedeb http://mirrors.ustc.edu.cn/ubuntu/ xenial-updates main restricted universe multiversedeb http://mirrors.ustc.edu.cn/ubuntu/ xenial-proposed main restricted universe multiversedeb http://mirrors.ustc.edu.cn/ubuntu/ xenial-backports main restricted universe multiversedeb-src http://mirrors.ustc.edu.cn/ubuntu/ xenial main restricted universe multiversedeb-src http://mirrors.ustc.edu.cn/ubuntu/ xenial-security main restricted universe multiversedeb-src http://mirrors.ustc.edu.cn/ubuntu/ xenial-updates main restricted universe multiversedeb-src http://mirrors.ustc.edu.cn/ubuntu/ xenial-proposed main restricted universe multiversedeb-src http://mirrors.ustc.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse

接下来从第一步——设置安装源那里开始，从头安装即可。
