It's kind of unfortunate how the "easy" works.
For a programmer sitting in front of a desktop that already has Linux on it, following those instructions would take less than five minutes. Easy.
For a typical Android user, they wouldn't know what they were looking at even if they had a Linux machine, which they don't. And would then get turned around by a simple typo like "apt-get-install" instead of "apt-get install" if they even make the attempt.
But because it's already "easy" for the people with the expertise to make it easier, the only people who could solve the problem are the people not experiencing it.
