Warning! Do not Update Ubuntu to the latest version 21.04

Updating Ubuntu to the latest version 21.04 On aaPanel will cause an error that the app in the library cannot be installed. All applications like: Openlitespeed, apache, ngnx, php, mysql.... will not be able to install. Thank you all

Why do you guys still using Ubuntu? It's never been stable, buggy as hell. I just don't get it, why?
It's already centos and debian. I'm using centos 7 mostly.
But never ever Ubuntu.
