That is why I see Ubuntu as a non-starter unless you are prepared to deal with it's crippled usage by default, because adding anything is a surefire way to have it implode on version upgrade. Meanwhile, on a rolling release, baring things that break for most everyone, you just upgrade when convenient and go about your day. I just don't see Ubuntu as anything that should be suggested to anyone w/out command line knowledge and strong Google-fu, because it's not if - but when will your system implode with Ubuntu.
