That's from Apr '16. For Raspbian Buster Lite
(https://www.raspberrypi.org/downloads/raspbian/) you'd need
Preliminary Stable Builds
(https://wiki.trinitydesktop.org/Preliminary_Stable_Builds,
http://mirror.ppa.trinitydesktop.org/trinity/deb/trinity-sb/dists/).
I'm not sure the specifics, but something like:

1) Add the Debian Trinity Repository sources (2 lines)
deb http://mirror.ppa.trinitydesktop.org/trinity/deb/trinity-sb
raspbian-buster deps-r14 main-r14
deb-src http://mirror.ppa.trinitydesktop.org/trinity/deb/trinity-sb
raspbian-buster deps-r14 main-r14

2) Add the GPG signing key
wget http://mirror.ppa.trinitydesktop.org/trinity/deb/trinity-keyring.deb
sudo dpkg -i trinity-keyring.deb
