What other media has shown linux?

Since you say media and not specifically show or movie.

There's a manga based on ubuntu: https://en.wikipedia.org/wiki/Ubunchu!

The story follows the activities of the three members of the Ichinomiya Prefectural High School's system administration club (part of the wider IT club). Each chapter is focused on a certain aspect of the Ubuntu operating system or a related topic, such as command-line interfaces, input methods, Linux Mint, or software licensing.
