I’ve seen people suggest Ubuntu without mentioning Kubuntu, but it seems like most people (especially gamers?) prefer KDE Plasma. I’ve seen people complain about Ubuntu’s GUI and lack of customization, but then no one suggests them to try Kubuntu instead. It seems like people just don’t know that Kubuntu exists.
Also as an aside, people often criticize how slow updates are on Ubuntu/Kubuntu/etc, but if you enable the backports ppa then it’s actually pretty quick!
sudo add-apt-repository ppa:kubuntu-ppa/backports


*buntu are mainly beginner distros. They work fine out of the box, but many long-term users don’t like them for ideological reasons.
The main advantage of Ubuntu over any other distro is that everything as an Ubuntu guide. The same is not true for Kubuntu, and if you stay in GUI, Ubuntu and Kubuntu share almost no similarities. The settings, the pre-installed default apps, all that differs greatly.
Thus the main reason for using *butnu is gone when using anything else than Ubuntu.
Which kinda sucks, because I like KDE much more.
They aren’t. Canonical enshittifies Ubuntu and the official flavors more and more. The hoops one needs to jump through (like OP’s PPA command because Canonical forbids proper updates) are not user friendly.
Steam Survey shows how Ubuntu’s relevance for home users continues to shrink and alternatives like Bazzite continue to grow.
Except UwUbuntu. We don’t speak of that thing here, or anywhere.
Edit: that was a bad joke, but it seems something like it (UwUntu) does exist! https://uwuntuos.site/
My people
I think Kubuntu is fine for beginners. Nvidia support is good, everything runs on it, and it’s got a stable release cycle
