I'm using Ubuntu 18.04.

So I tried upgrading hydrus and it doesn't start.
I was on 381 and first I tried upgrading to 389, then 383, neither of which worked.
I successfully upgraded to 382, then tried 383 again from there, but that also didn't work

Terminal error message, same each time:


./client

2020/03/30 02:41:04: hydrus client started
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.
