If you are searching the web if you can complete your PSI Proctored exam (e.g. CKA) on a Fedora machine, your answer is yes.

Even though the system requirements only allow ubunut, I completed the exam on a Fedora Workstation 40 machine as I couldn't be bothered to install it. You can also do a test exam beforhand which will use the same software as the live one. Just make sure you run on X11 as wayland screensharing is still not there for PSI.

Last tip: close the live-chat window after the security check in. Otherwise you're working with a very small test area.
