Ubuntu or Mint
Probably depends how you define things. Like, is Xubuntu Xubuntu or Ubuntu with Xfce included by default? How much change is necessary before it’s not “debian with added bits”?
I think a lot of people just got trolled in this thread.
Hannah Montana Linux is probably the most popular Linux distro.
In all seriousness, popularity isn’t necessarily the best metric for what you should run on your computer. Ubuntu might be fairly popular, but it also isn’t particularly good.
Ubuntu 100%, if you count how many distros are ubuntu based (and collaterally debian based), but I believe it is the most used one even if you only count official ubuntu releases
Maybe arch would be quite high, if you count the steamdeck as desktop (maybe), and the big increase on arch users in the past couple of years (wen’t from being rare to 1 in 3 users saying “I use arch btw”)
