I cannot install Ros to my computer

Hi, i am trying to install Ros to my computer. I am doing everything the steps say at Ros basics course, 14-appendix. But when i enter “sudo apt-get install ros-kinetic-desktop-full” to my terminal it says
Reading package lists… Done

The following information may help to resolve the situation:

What shall i do?

@husamcahit what version of linux are you using? Try following this installation guide:

@bayodesegun Perhaps this appendix needs updating.

Hi @husamcahit,

The error you are getting suggests that something is wrong the the sources list of your linux machine or vm:

  • Are you using the expected version of Ubuntu (16?).
  • Have you setup the sources list.
  • Have you run sudo apt-get update?

@simon.steinmann91 what do you suggest we update in that appendix, based on what you have seen? Thanks.

Didn’t you switch to melodic? The install instructions should be updated then.

No, we didn’t. We are still on Kinetic for this course (and most other courses except the ROS2 course).
You can run the following to confirm the ROS distro in use:

env | grep ROS
