Okay thats good to know. My quetion is their a difference besides GUI between ubuntu and Kubuntu and the other variants of ubunut. I saw online that they are not created by the official company so was wondering if they are safe and reliable to use.
The only difference between any of the *buntu’s is the GUI. Same with the variants of Mint - which are based on Ubuntu, but again with different desktops. Recently Mint diverged from Ubuntu a little, by removing some dummy packages which Canonical included which installed snaps instead of traditional Debian packages.
Also mint have a couple of variants based on Debian, rather than Ubuntu.
Ubuntu is derived from Debian.
But again, other than the desktop environment, any Debian based system is pretty much the same as any other.
Also the *buntu and *buntu derived distros support ppa’s, where’s purely Debian derived distro’s do not. That’s the only other major difference I can think of between Ubuntu derived, vs Debian derived distros.
Even more generically - the differences between most Linux distros are purely cosmetic - different desktop, different package management systems, different default set of software pre-installed, maybe a different init system. But Underneath it all, they’re all pretty much the same.
The only other difference are the ethos behind a distro - e.g. attitude to inclusion of non free software, easy install with little user interaction and a sane set of defaults vs trickier install, with more manual interaction to give users fine tuned control of what gets installed. Etc.
And then there are specialised distros that include software for a particular purpose.
E.g. General, every day use, server use, low power/lightweight resource usage, penetration testing, forensics, scientific computing, engineering, Audio/video production etc.
