Hi guys i have Ubuntu 18.10. This is the procedure that i have done in the terminal. I paste this:

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

then i paste:

sudo apt-key adv --keyserver hkp://ha.pool.sks-keyservers.net:80 --recv-key 421C365BD9FF1F717815A3895523BAEEB01FA116

when i do sudo apt update

I receive this error

Hi guys i have Ubuntu 18.10.

And that is why the installation procedure is failing, because Ubuntu Cosmic (18.10) is not supported by ROS Melodic. Only Ubuntu Bionic (18.04) (and 17.10) are supported.

See REP-3 - Melodic Morenia (May 2018 - May 2023).
