Missing some dependency？ #21
Description
os: ubuntu20.04
error: QSocketNotifier: Can only be used with threads started with QThread
PulseAudioService: pa_context_connect() failed
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: vnc, vkkhrdisplay, minimal, wayland-egl, linuxfb, eglfs, offscreen, minimalegl, xcb, wayland.
other info: I try sudo apt update && sudo apt install -y xorg libxcb1 libxcb1-dev libxcb-xkb1 libxcb-xkb-dev libx11-dev libx11-xcb-dev libxcb-xkb-dev libxcb-util0-dev libxcb-icccm4-dev libxcb-keysyms1-dev libxcb-image0-dev
note: I use the xfce and Remote Desktop, whether it will result in the error above.
Can you give me some advice, thanks a lot.
