You are not running a distribution from the Ubuntu family but from the Debian family (Raspbian), this is not following the same release cycle. Hence the distribution Raspbian/buster could not be found by add-apt-repository

I would suggest than you add manually the PPA repo as explained https://launchpad.net/~nathan-renniewaldock/+archive/ubuntu/flux

You might need to add sudo in order to run the following

echo "
deb http://ppa.launchpad.net/nathan-renniewaldock/flux/ubuntu eoan main 
deb-src http://ppa.launchpad.net/nathan-renniewaldock/flux/ubuntu eoan main
" > /etc/apt/sources.list.d/fluxgui.repo
apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 4cdb129629a4b41a
apt update
apt install fluxgui
