Just to double-check, did you image your Pi with Raspberry PI OS (Legacy) Lite?

The error you encountered is similar to something I've seen before when installing these LED Matrix repositories against a Raspberry Pi with a Desktop environment. I'd only recommend running against a Legacy Lite version.
