This is a good question.

I have found a few people asking related questions:

https://askubuntu.com/questions/1422818/ubuntu-ubuntu-flavors-ubuntu-remixes-ubuntu-derivatives-whats-the-differen

https://askubuntu.com/questions/452182/is-it-possible-to-know-which-recognized-flavor-i-am-running-using-terminal

https://unix.stackexchange.com/questions/384796/how-to-determine-which-ubuntu-flavor-im-on

The last one looks positive. The top-voted answer does not work for me though.

````
$ dpkg -l '*buntu-desktop' | grep ^ii
````

I get:

````
dpkg-query: no packages found matching *buntu-desktop
````

I found this worked:

dpkg -l '*-desktop' | grep ^ii

But there's noise in the response because this matches other packages.

I reckon there is a need for some kind of official solution here.

The hints in that last link may help.
