Qt error when trying to run remotely via VNC

[tredondo]

After failing to run on Ubuntu 18 (#7190), I've created an Ubuntu 20 VPS cloud instance, installed xvfb, x11vnc, and all dependencies (including the optional ones). I can run xeyes remotely and see the output locally with a VNC viewer.

The problem is that trying to run the keepassxc binary gives the following error:

./keepassxc: /lib/x86_64-linux-gnu/libQt5Core.so.5: version `Qt_5.15' not found (required by ./keepassxc)

How can I run KeePassXC remotely?

You built keepassxc using Qt 5.15, but are trying to run it on a machine that doesn't have that version available. Please just use the binaries we provide. AppImage, Snap, or PPA.
