What is the best way to install a minimal Ubuntu?

I would like to know what is the best way to install a minimal Ubuntu setup similar to Arch. Now seeing that the mini.iso is gone is the Ubuntu Server a good option or something else? Thanks in advance.

>Solution :

You still can get mini.iso of Ubuntu 20.04 LTS from

http://archive.ubuntu.com/ubuntu/dists/focal/main/installer-amd64/current/legacy-images/netboot/

and then build any type of system on top of it using Aptitude and other CLI/TUI-based lightweight tools without huge massive Snaps and cloud init.
