I can't do the makefile (third part of the install process)

If you don’t see SUCCESS message in the end, then building did not finish properly.
In that case, take a look into /home//Vídeos/programas/UnrealEngine-4.24/Engine/Build/BatchFiles/Linux/BuildThirdParty.log for details.

No third party libs needed to be built locally
********** SUCCESS ****************

then, I write in the ubuntu terminal: make

Setup successful.
