Hi all, I have been trying to follow the guide to installing ROS Kinetic using ubuntu 16.04 as mentioned in the guide: http://wiki.ros.org/Installation/Ubuntu However, when I reach the stage to install keys I continue to have errors. I would appreciate any help.

jt@DESKTOP-3055SML:~$ sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'

Im not sure how to enter all the text into a comment with the correct formatting, and have instead put a screen capture on imgur. Hope this will do. link to imgur

copy from your terminal, paste into your original question (use the edit button/link near the comments) select pasted text, press ctrl+k or the Preformatted Text button (the one with 101010 on it).

Please do not use screenshots to show console text. See also the support guidelines.

Ok, hope that is better? I've added the code for all three substitutions

I do not know the exact solution to your problem. It may just be a network issue or a problem with your package list.

I did however find a workaround/second method for installing keys. Follow the following steps:

  1. Visit this link
  2. Copy the block after the title Public Key Server -- Get "0x5523baeeb01fa116 " to a file (lets say abc.txt)
  3. Run sudo apt-key add abc.txt
  4. If it works, you will receive OK as output
  5. Run sudo apt-get update

Seems to be the same problem, I have added the errors to the original question

Are you behind a (corporate) proxy or some other form of firewall?

This is my personal desktop pc and am not using a proxy, I have disabled my windows and kapersky firewalls but still the same problem.

+1 for the effort @ameykasar but this is not necessary.

@JThan: try the following command:

wget http://packages.ros.org/ros.key -O - | sudo apt-key add -

@gvdhoorn Sorry for the late response, Result:

Or I get,

Giving up.

With that output I really start to get the feeling you're behind some kind of firewall or proxy and that is interfering with your connections to packages.ros.org.

You'll have to verify that or find a work-around.

Is it influenced at all by the fact I am running Ubuntu 16.04 LTS (from microsoft store)? Any known problems with this?
