qt.qpa.plugin: Could not find the Qt platform plugin "xcb" in ""

[Pandapip1]

When attempting to start uefitool, I get the following error:

gavin@gavin-ideapad-1:~$ uefitool 
qt.qpa.plugin: Could not find the Qt platform plugin "xcb" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

From my limited research it appears this is due to the fact that I am not running an X11 session (I am using Plasma Wayland instead).

Check if any solutions listed here will fix it for you.

Also, providing more details about your OS version and environment would be helpful.

[Pandapip1]

The OS that I installed was elementary OS, but I've made so many customizations to it that basically all the evidence that's left is the apt sources, the app store, and the neofetch data.

Again, the problem is almost certainly that I'm using Wayland instead of X11. Never mind, also fails to launch on XOrg.

Here's hopefully all the information on my system you could ever want:

Now you have a different plugin failing, so it feels like there's something wrong with your Qt installation. Can you run UEFITool with QT_DEBUG_PLUGINS=1: QT_DEBUG_PLUGINS=1 uefitool and share the output here?

[NikolajSchlej]

Installed elOS 7.1 Horus on emulated x86-64 QEMU machine, then installed UEFITool from Flatpack like this:

• flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
• flatpak install uefitool

It installed some additional components and the resulting app runs just fine.
