The Unity platform for learning comes with the Microgame FPS asset in order to learn the Unity 3D game engine.
I started to use this microgame on Fedora 33 Linux distro with the Unity editor version 2020.1.10f1 and the Unity game engine version need by this microgame.
I got errors in the build process when I try to build on android, Linux, and web platforms.
The errors are these:
Assets/FPS/Tutorials/BuildAndPublish/Criteria/PublishCriteria.cs(1,13): error CS0234: The type or namespace name 'Connect' does not exist in the namespace 'Unity' (are you missing an assembly reference?)
Assets/FPS/Tutorials/BuildAndPublish/Criteria/PublishCriteria.cs(12,16): error CS0246: The type or namespace name 'ShareWindow' could not be found (are you missing a using directive or an assembly reference?)
The easy fix is to delete the Tutorials folder, make all settings and, rebuild.
