I am trying to install ROS2 foxy following the tutorial (https://docs.ros.org/en/foxy/Installation/Ubuntu-Install-Debians.html)
However, when I arrive to the part of:
sudo apt install ros-foxy-desktop
I receive the following message
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package ros-foxy-desktop
I am trying to install it in Ubuntu 20.04 64 bits
