I followed this guide here.

Getting the following error.

sudo add-apt-repository ppa:veyon/stable
Traceback (most recent call last):

On raspian, you should add the PPA to your APT configuration (sources.list). For stretch you should add

deb http://ppa.launchpad.net/veyon/stable/ubuntu xenial main
