@beardalaxy @hideki ok you did this to yourself:

People usually use the term linux distro, because majority of distros present themselves as Name Linux where the linux is only kernel the operating system is GNU so unless you are referring to linux distribution such as linux-libre by the Free Software Foundation Latin America that everyone should be using instead of mainline then you should say GNU distro where GNU being the userland that holds everything together and is therefor called the Operating System with linux being just one of it's supported kernels.

All operating GNU Operating systems has to follow GNU FSDG <https://www.gnu.org/distros/free-system-distribution-guidelines.html> requiring following established values such as not including code and packages that is not GPLv3 complying to be considered GNU and thus "GNU distribution" not "Linux distribution" when referring to the OS.

Ubuntu is just disgusting reskin of Debian both of which violate GNU FSDG which is why GNU is maintaining a fork called GNU Trisquel instead thus Ubuntu is not linux distribution because it is not complying with GNU FSDG and therefor legally call itself a Ubuntu GNU/Linux and should be avoided..

Personally i would rather use Windows as ubuntu is terrible OS filled with malware that is very very slow on security updates and should be at all cost avoided in production environment.. or any environment tbh

And apt-based distros are obsolete since like 2008 it's very limited and inefficient package manager that should be avoided.. consider using GNU Guix instead (can be installed and cleanly removed on majority of the distros so that you can try it e.g. apt-get install -y guix).
