What killed my interest in Linux in highschool. Kept trying to get Ubuntu working but couldn’t get the internet to work for anything. Given that every help guide boiled down to “Go to this website and download x” and I didn’t have internet because… no wifi, I ended up getting frustrated enough to quit the whole thing. Maybe someday.
This was back in 2007-2008 ish. I believe the Ubuntu version was feisty fox at the time, if that helps.
