The 'flavours' of Ubuntu are a sort-of second-class citizen.. Canonical, obviously, want people to enjoy their flagship experience, which is Ubuntu with GNOME, snap and all the other stuff they've built into it. But the 'flavours' of Ubuntu, Xubuntu, Lubuntu and Kubuntu exist because there's a passionate-enough group of people who want to experience all the goodness of Ubuntu, but get their own environment.
In my case, I'm using Kubuntu, which is Ubuntu but with the rather slovenly GNOME replaced with a much slicker KDE Plasma 6. Now, there are other distros that use KDE, but the benefit of using a 'flavour' of Ubuntu is that whenever Canonical make a new version of Ubuntu, the flavours are updated too.
When I was looking to shift to a Debian-based distro with KDE, and Kbuntu floated up to the top of the search results, it was pretty hard to find the actual correct install for it. The distro's main page looks more like a wiki. It's certainly not as polished as the pages for Mint or Ubuntu itself....
So, knowing that the versions are called YY.MM where MM is the release month which alternates 04 and 10 for the two semi-annual releases, I googled "Kubuntu 25.10" to get the release from October, and found there was indeed a release. I downloaded it, installed it, and it's all working pretty nicely....
BUT what I didn't realise was that 25.10 is still considered "development", and there are some little niggles with it... Like, for example, Steam just stops throwing up new windows from time to time, and I need to restart it... Or some of the themes and packages are broken. Adding a printer wouldn't work because the distro 'forgot' to add me to lpadmins, so cups wouldn't accept my password :-/ sigh...
I really should have installed the 24.04 LTS version for stability, but I was so fed up of Linux Mint's behind-the-curve kernel versions that I wanted a distro that was up to date.
Well, 90% of things are going really well, but having a bleeding-edge distro does come with its pitfalls.....
So, with the kids now experiencing the same issues I was facing with Mint (some games not Alt-Tabbing, or just plain hanging), and I'm considering moving them to Kubuntu, I'm really starting to wonder if maybe I should give them 24.04 and see if that resolves the game issues, and if not, maybe bite the bullet and give them 25.10 and let them know that there may be Krakens.......
