PSI Browser won't work on Ubuntu 25.10, Xubuntu 25.10, nor Ubuntu 26.04

After booking a Linux Foundation exam slot I was given the instructions to test the PSI Browser, and despite all major versions of Ubuntu being listed as officially supported, I cannot make the app work in any case.

The installer will try to launch the app, this will fail with a segmentation fault, and the installer will detect this and uninstall everything.

I managed to hack this whole process and get the app installed nevertheless, and by adding some extra CLI flags I managed to launch it, but at some point it shows “Error occurred getting org configuration" and gets stuck there.

I tried with Ubuntu 25.10 (Wayland), Xubuntu 25.10 (X11), and Ubuntu 26.04 (Wayland). None of these systems worked.

I already opened TCCS-172649 but got no response yet. What should I do?

    Hi @juanluiskedro,

    Opening a ticket was the correct step, as the Customer Support team can assist you with this. It can take several business days (excluding weekends and holidays) for them to respond, depending on volume. Thank you for your patience while they work to assist all students.

    I sent them an email on april 28th too, no response at all, not even an confirmation email.
    They list ubuntu 26.04 as an supported operating system, yet their PSI exam tool only supports X11 which is removed from Ubuntu 26.04.

    It'd be great if the Linux Foundation worked more closely with PSI on validating their requirements, as someone who just wants to make an exam this is very demotivating. As they don't always offer physical locations either I am now made responsible for installing a different OS on a spare system just so I can use their software..

    What was the end result of this? I also had many technical issues with the PSI browser. I was able to get through check-in with the proctor, but when the proctor did the hand-off to what I'm calling the "Exam Tutorial" that introduces the exam UX and features, the browser became unresponsive. Almost like a modal dialog was blocking interaction with the interface. I went through this 3 times, without any success on Ubuntu 26.04.

    I did similar as you and installed windows on a spare system and currently I'm waiting for my retake.

    I can confirm that the PSI Secure Browser is not reliable under Wayland either.

    I used Fedora 44 with Wayland and successfully completed the PSI browser system checks three times before the exam. However, when the actual exam started and the introduction to the exam UX and features began, the browser became completely unresponsive and I could no longer interact with the interface.

    My exam attempt was immediately terminated.

    I opened a support ticket with the Linux Foundation right away and explained the issue. Fortunately, they granted me a new attempt at the CKA exam.

    For my second attempt, I will use a notebook running Ubuntu 24.04 with X11 to avoid running into the same issue again.

    It is frustrating that the pre-exam system checks can pass successfully while the browser still fails at the actual exam start. It would be helpful if PSI and the Linux Foundation could investigate this issue and provide clear guidance on which Linux desktop environments and display servers are reliably supported.
