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:

  1. exam@work:~$ ./PSI-SecureBrowserSetup_pd_FMDEFKFVBX12QFN2JJXDAQVPPG-01JKQ87VMMR8HDM0YFPW96P6JR --debug

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

    1. exam@work:~/psi/.config/com.psiexams.psi-bridge-secure-browser$ ./PSIBridgeSecureBrowser.AppImage 
    2. [23718:0210/075121.843065:FATAL:setuid_sandbox_host.cc(163)] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that /tmp/.mount_PSIBri29jo24/chrome-sandbox is owned by root and has mode 4755.
    3. Trace/breakpoint trap (core dumped)

    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:

    1. Error occurred getting org configuration.
    2. 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:

    1. Error occurred getting org configuration.
    2. 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

    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.
