can't install ros on ubuntu?
I'm new to Linux, so I followed the install instruction, created a source list and generated key.
On updating
sudo apt-get update

I got this error. On further following the steps i ended up with
sudo apt-get install ros-kinetic-desktop-full

so please help.
Please post the contents of
/etc/apt/sources.list.d/ros-latest.list.Thanks for reply. Here are the contents: $ cat /etc/apt/sources.list.d/ros-latest.list
deb http://packages.ros.org/ros/ubuntu xenial main
That looks fine. Does
apt-get updatestill give an error?yes it dose. are there any alternatives to install ros.
Yes, you can install from source. But it would take a while to compile. For the benefit of you and anyone else who has the same problem in the future, I hope we can fix the actual problem.
What does
lsb_release -aprint?According to this question, running
apt-get cleanand then runningapt-get updateagain may work. Also deleting/var/lib/apt/lists/*also helps, apparently.thanks a lot. it worked.
