Conecting BTT LCD to Octoprint

Cannot configure the LCD screen in to work with Octoprint !

I started by following the online tutorials, when I type in the first command:
sudo apt-get install libgtk-3-0 xserver-xorg xinit x11-xserver-utils

I get this message: Screenshot 2020-09-07 at 02.27.08|570x500

Sorry I am a noob regarding Raspberry so would appreciate any help!

Have you tried sudo apt —fix-broken install, as suggested (twice) in the output you posted?

You can also run the OctoPi 'install desktop' script, which will do it for you - although if something is corrupted, then it will still tell you and you will have to fix it.
