I am trying to install ROS KINETIC on Ubuntu 16.04, but every time after 94% installation it stuck,and gives following error....

The following packages will be upgraded: libavcodec-ffmpeg56 libavformat-ffmpeg56 libavutil-ffmpeg54 libglib2.0-0 libglib2.0-bin libgssapi-krb5-2 libicu55 libk5crypto3 libkrb5-3 libkrb5support0 libssl1.0.0 libswresample-ffmpeg1 libswscale-ffmpeg3 libtiff5 libxml2 15 upgraded, 700 newly installed, 0 to remove and 246 not upgraded. Need to get 32.3 MB/449 MB of archives. After this operation, 2,169 MB of additional disk space will be used. Do you want to continue? [Y/n] y Err:1 http://packages.ros.org/ros/ubuntu xenial/main amd64 libvtk6.2 amd64 6.2.0+dfsg1-10build1+debian11.1+osrf1 Connection failed E: Failed to fetch http://packages.ros.org/ros/ubuntu/po... Connection failed

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

Then when I open terminal I get this message. I have no idea how to solve it. Because of the error I can't install ROS again.
