Doesn’t even have to be a “class of idiots”. It would be enough if stuff didn’t just sometimes break, seemingly randomly. (It’s not quite random, obviously.)
Recent example: I had OpenSuse TW recommended because of its reliability. First tip: install codecs, which requires adding the Packman repository. Now, simply updating threw up errors several times because Packman and the other repositories are apparently not in sync, and some dependencies would break if I updated. (Waiting a few days “fixed” it, but still shouldn’t happen.)
Depending on which update method you use (Yast/Discovery/zypper/update widget) you get different error messages, most of which are not informative. This is for an established distribution known for its reliability, and this alone would keep me from ever recommending it to normal users, even moderately tech-savvy ones.
Things are getting better, but I’m still shopping around for a distro that just works. Perhaps that new Fedora version, or one of the immutable ones, now that they are getting popular.
The solution I’ve sort-of found is to go to communities of Arch-based systems instead of Arch itself. The same solution should work in most cases*, and the communities are more newbie-friendly.
*Depends on how close to Arch the distro is in this aspect/subsystem. The Manjaro community is probably less likely to offer AUR based solutions, since the AUR can be unreliable/unsafe on Manjaro.
