KDE liveinst crash

Fresh Fedora 43 KDE live ISO boots well from USB (17.12.2025) , but “Install to Hard Drive” application crashes within few seconds after displaying empty white window. When I run the liveinst in console, it crashes with core dumped and following log;

Starting installer, one moment…

anaconda 43.44-3.fc43 for Fedora 43 started.

  • installation log files are stored in /tmp during the installation
  • shell is available on TTY2 and in second TMUX pane (ctrl+b, then press 2)
  • when reporting a bug add logs from /tmp as separate text/plain attachments

This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vkkhrdisplay, vnc, wayland-egl, wayland, xcb.

Could anyone please advice what the liveinst tool is trying to do?
The libxcb-cursor0.so.0 can be found in /usr/lib64/ directory, could it be wrong file or corrupted in the live CD? Could it be a matter of missing or wrong LD_LIBRARY_PATH variable?
Thank you.

What is your hardware?

Install inxi then can you get the output inxi -Fzxx and post here (as text)?

(Sidestory: I broke my grub2 settings for Fedora 41 KDE with plasma which I had been upgrading since some Fedora 33 or so, and I hoped to simply install 43 over it. I have not figured yet how to repair 41.)

I wonder if the issue is the nvidia gpu.

Does the f42 live installer work?

5

I wonder if there may be a bios update for that system. The current version is dated 02/15/2017.

There have been several cases where a bios update has resolved users issues.

6

Let me try 42. I have found live USB KDE 42 here (https://download.fedoraproject.org/pub/fedora/linux/releases/42/KDE/x86_64/iso/Fedora-KDE-Desktop-Live-42-1.1.x86_64.iso), I can try. It’s possible that GTX 1xxx models become too old already. Even bazzite OS does not support them. I’m going off now for Christmas for a week, though, but I will definitely let you know.

My attempts to use Plasma on Wayland failed before, it was not working with nouveau drivers then. In 41, it was always X11. I need to check 43 once more, it is odd that live 43 system works, but QT is trying to initialise XCB QT plugin for X11.

Thank you.

I don’t know the details of what you found, but F41 Plasma Wayland worked fine for me on nouveau (for a week or so before I got round to installing the proprietary drivers).

Anyway, what jumps out at me here is this:

Slitherer is the cut-down browser in which the installer runs on the KDE live ISO. I wonder why it thinks it needs to run as an X11 app via XWayland, rather than a native Wayland app?

Actually, your issue looks similar to this Bugzilla ticket (on the MATE spin) -

One workaround would be to force the use of Firefox rather than Slitherer to render the Anaconda web UI.

In a terminal in the live environment, sudoedit /usr/libexec/anaconda/webui-desktop

In that file, there should be a line that sets a variable called DEFAULT_BROWSER_CMD. Change that line to…

DEFAULT_BROWSER_CMD=firefox

…then save the file and try liveinst again. (Source for this suggestion.)

Thank you P G for the link, it indeed is the same case - the crash at the same line of webui-desktop application, just slightly older GT 730 card. Sorry, I did not notice your workaround suggestion and tried the F42 live installer yesterday. It worked well, I’m going to use F42 until it becomes EOL. I’m going to put a note to that Bugzilla issue.

There seems to be another obstacle looming over older GT and GTX cards in the future - Arch Linux - News: NVIDIA 590 driver drops Pascal and lower support; main packages switch to Open Kernel Modules

Thank you, guys.
