如何解决Debian buster qt.qpa.plugin 无法加载 Qt 平台插件“xcb”

您好，我针对这个问题运行了许多参考教程，但没有一个能解决我的问题。 当我安装笔记本电脑模式工具时出现了问题 并尝试启动 GUI。

sudo apt-get install laptop-mode-tools

 pkexec /usr/sbin/lmt-config-gui
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: eglfs,linuxfb,minimal,minimalegl,offscreen,vnc,wayland-egl,wayland,wayland-xcomposite-egl,wayland-xcomposite-glx,webgl,xcb,dxcb.

但这也能让我了解如何解决其他软件的 qt 问题。

我跑了

    sudo apt-get install '^xcb*'
    sudo apt-get install build-dep qt5-default
    sudo python3.7 -m pip install pyqt5 pyqt5-tools pyqt5-plugins
    sudo ln -s /usr/lib/x86_64-linux-gnu/qt5/plugins/platforms /usr/bin/platforms
