RcloneBrowser - "Config" button not working on Ubuntu 18.04 & 20.04

[Marella139]

After installing RcloneBrowser (v1.53.3) on both Ubuntu 18.04 and 20.04 (x64) I can't seem to bring up the Config option on Rclone GUI since the button is unresponsive after clicking on it.

Note that the same option works fine on Ubuntu 16.04.

These are the output I got after trying to run rclone-browser on CLI:

user@rapidseedbox:~$ rclone-browser

[sudo] password for user:

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, xcb.

Aborted (core dumped)

P.S. I don't have rclone.conf file so I can't make any bigger changes to the service.

can you install the version 1.8.0?

@c4tom Thanks for the reply. I've already had that version of GUI installed.

Why are you running it as root? That seems like a bad idea...
