apt – Chrome Remote Desktop

I’m trying to set up Chrome Remote Desktop on Ubuntu 21.04. It downloads a .deb file which I then try to install via Terminal.

It starts installing but finally I get this error:
libdvd-pkg: apt-get check failed, you may have broken packages. Aborting…

I get this error quite a lot when trying to install apps but I don’t know how to fix the problem. Does anyone have suggestions to fix broken packages?
