@Solid Rhino - apologies if the PINN versions of the mentioned OSes are not quite the latest ones. It takes quite a while to convert and test each one and I'm rather swamped at the moment. Normally an installed OS can be easily updated once a version has been installed.
Details of how to convert an OS for installation by PINN are detailed in the README_PINN.md
file on github, and in my wiki
If you have the time to convert any newer versions, I am always ready to update my images with new tested versions so feel free to send them to me so that everyone can benefit. Otherwise you can host them your self by creating your own os_list_v3.json file, or simply install them from a local USB stick.
