I can understand what u going thr.
Many types and versions.
Some  use firefox some chromium as pre-installed
There is a way to use immediately and project into the future
using Imager. Images of the OS u want'
U start with ubuntu 20.0.4 from where we left off.
Now we can update that.
This is the basis of getting imager snaps for various softwares.,
U can manage Disks  really manage like create image of ur system.
You can also Gparted your disks in another.
Raspberry Pi has everything hidden like programming all sorts etc.
We r the ones lacking in knowlege and skills./
