linux appimage problem

Hi, i'm trying to launch the appimage file in lubuntu 18.4 with the command line given
(chmod a+x ./rpcs3-v0.0.5-7195-23b52e1b_linux64.AppImage && ./rpcs3-v0.0.5-7195-23b52e1b_linux64.AppImage) and i get this error:

this application failed to start because it could not find or load th Qt platform plugin "xcb" in ""
available platform plugins are: xcb.
reinstalling the application may fix this problem.
aborted (core dumped)


I don't kow what to do next.

Hi, you need to install your xcb libraries, just run `sudo apt-get install libxcb*`
