I known that the uname -o command will display the operating system. But when I run that on Ubuntu 20.04, I get

GNU/Linux

not Ubuntu. Why is it like this?

Ubuntu is a GNU/Linux distribution.

man uname tells me the -o options report

 -o, --operating-system print the operating system

To me that is a valid answer, Ubuntu shows instead who packaged up the GNU/Linux operating system you are using.

I'd usually use lsb_release -a to view details about what GNU/Linux I'm using, for my system I get

guiverc@d960-ubu2:~$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu Groovy Gorilla (development branch) Release: 20.10 Codename: groovy
