While excecuting step by step this installation guide http://wiki.ros.org/melodic/Installation/Ubuntu I get this message:

E: Unable to locate package ros-melodic-desktop-full

also tried the kinetic version of ROS but again it was unable to locate the packages.

ROS melodic is compatible with the following distros: Artful (17.04) and Bionic (18.04). You most probably need to wait until May 2020 for Noetic.

If you want to stick in 19.10 try docker containers on top, although if you're a beginner is better to avoid this complexity.

  • after trying Installing from source : in this step ./src/catkin/bin/catkin_make_isolated --install -DCMAKE_BUILD_TYPE=Release getting this error :Could NOT find PY_em (missing: PY_EM) – johN Dec 10 '19 at 15:26
  • I recall in the past have faced a similar problem but I don't remember the solution. I think that you should install python-empy. I found this related [post](https://discourse.ros.org/t/catkin-make-error-building-package-on-machine-after-image-install/3549) in case that helps... – angelos.p Dec 10 '19 at 17:24

    It's really hard to install it from sources. Finally it was python-empy but after that it stops again finding some other errors. I already have find the solution for 4 errors but in progress is 35/237. – johN Dec 11 '19 at 07:05
