qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found. #439

Open kruthoff opened 6 months ago

kruthoff commented 6 months ago

Version 0.76 doesn't start anymore on Pop!_OS 22.04 LTS x86_64. I've purged the app and have reinstalled it, without luck.

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: xcb.

Is this running on Xorg or Wayland as display server?

Running on Xorg.

try running export QT_QPA_PLATFORM=xcb before starting it from the command line

paulrtcsjh commented 1 month ago

I have this issue too, same exact message. I am running Ubuntu 24.04 and using Xorg. Running export as LackingCats suggested did not change the result.

Running into the same issue on Ubuntu 22.04.05 LTS.

Doing the export QT_QPA_PLATFORM=xcb didn't fix it.

I was having the same problem on a fresh Linux Mint 22 install, I solved it by installing qt5ct, setting QT_QPA_PLATFORMTHEME=qt5ct in /etc/environment and installing this: sudo apt-get install -qq libglu1-mesa-dev libx11-xcb-dev '^libxcb*'

I'm not sure if it is all needed but it was failling before the last round of installs. Hope it helps !

For me it was the missing libxcb-cursor0

 sudo apt install libxcb-cursor0

Was enough to solve the problem.
