Hello Everyone!

My exam is due in 2 hours, and I was trying to install the PSI Secure Browser onto my Kubuntu 24.04 computer, but the installer crashed on me with this:

    I tried to download the tar file from the output above, and run the AppImage from it, but no luck:

    exam@work:~/psi/.config/com.psiexams.psi-bridge-secure-browser$ ./PSIBridgeSecureBrowser.AppImage

    I got one step further: I used the --no-sandbox option to the AppImage, and now it launches, but am getting the error on its UI:

    Error occurred getting org configuration.
Please try again or try reinstalling.

    I also tried using another (Windows) desktop machine, but that does not have a built-in webcam or microphone. I do have an old webcam but Windows 10 doesn't recognize it, so I guess I am out of options, as this setup won't work with PSI.

    In the last step of my utter desperation, I tried to load up a vanilla, live Ubuntu 24.04.1 onto my machine to rule out any local customization interfering with the browser.
    Unfortunately the PSI Secure Browser won't work on a stock live Ubuntu 24.04 either.
    I get the following error:

    I also tried the --no-sandbox on the AppImage, that the installer was trying to download, but it is complaining about FUSE support.
    When unpacking it with --appimage-extract, I get the same error as on my original Kubuntu install:

    Error occurred getting org configuration.
Please try again or try reinstalling.

    At this point I am giving up. This will be a no-show.

    Hi @fcioanca

    I already opened a ticket with Customer Support.
    Though I was already ready to give up, after trying several machines, someone had a stroke of genius and suggested trying a MacBook Air I had laying around, and that worked well enough so that I was able to start the PSI browser and log into the PSI exam environment, but that happened only like 5 minutes before the start of the exam.
    So in the end I was able to attend the exam, though starting and finishing with a 30-45 minute delay.
    The PSI people were kind enough not to make a problem about it.
    The PSI exam environment still had its much talked about difficulties, and overall I was unfamiliar with the Mac shortcuts for special characters, so that added a bonus on difficulty for me.

    Best Regards,
    János Szigetvári

    In the meantime I got confirmation that I managed to pass the exam.

    I just had the same problem with a fresh ubuntu 25.04 and a fresh kubuntu 24.04 installation. To fix it, have disabled and uninstalled apparmor (and snap support). Now it is working.

    For anyone else on Ubuntu 24.04 running into this error: I had the same issue and I realised that I had missed this instruction from the docs: https://helpdesk.psionline.com/hc/en-gb/articles/4409608794260-PSI-secure-browser-and-Chrome-Extension-System-Requirements

    If you are using an Ubuntu computer- do not launch the browser from the console. You will need to "run as a program" from the desktop.

    Then the PSI browser started properly for me.

    this is still broken on Ubuntu 24.04 LTS. lack of instructions is rather frustrating.

    I had a crash during the Exam with Ubuntu 24.04 - it just asked to save the work and closed the window.
    So I decided to go back to Kubuntu 24.04.03 LTS. And found this forum while troubleshooting this bloody PSI secure browser.

    But it's quite easy.

    • The good news is that unlike Ubuntu, Kubuntu installed with X11 by default. So no need to disable Wayland.
    • The Secure Browser crashed because of apparmor. This is also easy: sudo apt remove apparmor and Reboot for the apparmor to be completely disabled.
    • As recommended, unzip and run from the Desktop (without using any konsole or file manager) since you should have no other app running.
    • The third and last odd thing is that it mentioned a prohibited program on my blank/fresh kubuntu install: mail.ru. I didn't see any process like that, but clicked on "Terminate & recheck" from the PSI Secure Browser and it passed all tests.

    Thanks for the heads up with the apparmor.

    Quick update to my last point about mail.ru. This is caused by the geoclue-2.0 service.
    So after installing Kubuntu, we need to remove both apparmor and geoclue-2.0:
    apt remove geoclue-2.0 apparmor then reboot and everything should be fine for the exam.

    Additional tip: Pick a camera with good quality & autofocus, because you're ID card must be readable. I initially overcome this problem by taking a lens of +3 dioptries that I placed on the camera lens just for the focus on my id-card, eventually buying a good Razer Kiyo camera (~45€) for my following tests. Also using the microphone of the camera did an excellent job (no speaker, but we don't need speaker for the tests)

    Hi, I had the same issue with PSI Secure Browser (running ubuntu24), and I fixed it with

    sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0

    Thanks! It seems you saved my exam! At least the tutorial exam could run successfully after issued suggested command. I hope tomorrow will go the same in the real exam too. Have fun! :)

    Thanks a lot for all the hints provided here.

    sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0

    Fixed the problem also on my machine (Ubuntu 24.4)

    For the moderators, this information must absolutely be included in the instructions for taking the test and setting up the PSI environment.
    Please update instructions to include that;

    • On Linux, psi installer shall be extracted and the run from desktop, not terminal
    • On Ubuntu, the apparmor tweak needs to be run prior to running the installation script

    You deserve a hug. The support guys couldn't provide an idea or help. I switched laptop few seconds to the exam. The app crashed after 50 minutes in the exam as well. Lost 20 minutes, got disoriented. Nervousnes set in and the support guys didn't help either. Bottom of the story, got a failing score.

    sudo sysctl -a | grep apparmor

    Before launching the psi browser

    Disable restriction

    sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0

    when you are done with the exam

    Enable restriction (secure default)

    sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=1
