It's not fair to compare a specialist distro like Liberte, with a single developer behind it, to Ubuntu, with a 500-employee company and a community of 20 million users behind it. If you have a problem with Ubuntu, there is almost certainly a bug report (or 2 or 3) on Launchpad and a thread (or 2 or 3) on the forum by the time you Google it. Ubuntu is balls easy compared to Linux 10 years ago. It's easier to install and learn how to use than Windows, it's just that everybody already knows how to use Windows and they're accustomed to the Windows way.
