When I start the app on Ubuntu 22.04.2 LTS I see this:

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/home/opt/AmneziaVPN/client/plugins//platforms:" 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, offscreen, wayland-egl, linuxfb, minimal, wayland, minimalegl, xcb.

Aborted (core dumped)

Found the solution on askubuntu:

ldd plugins/platforms/libqxcb.so  | grep -i "not found"
	libxcb-cursor.so.0 => not found
	libxcb-cursor.so.0 => not found

So I run apt install libxcb-cursor0 and it now starts. I guess there is a bug in the app installer...

Oups, just noticed this in the release notes.

Maybe add it to the website for better visibility?..
