Yes, I recommend the book as well. Don’t ask me why though. I tried quitting smoking many times using many different methods but always failed. On a whim I got the Alan Carr book and read it. I read it in bursts over a month or two. There was nothing interesting in there. Nothing I didn’t already know. I finished it and quit smoking. The next day I relapsed and smoked again. I reread the last few chapters and quit again, this time using nicotine patches. I quit the patches within a day because they made me feel sick. I never smoked again. It’s been 7-ish years and I haven’t had any inclination to smoke again. It went from one of the hardest things to one of the easiest things to do. I don’t care if people smoke around me, it doesn’t bother me anymore. I still don’t know why the book works, but it did for me.
All the good stuff from Ubuntu has mostly been upstreamed into Debian. And Debian’s rekease cycle is much faster these days than it was back then. So, just run Debian.
