Installing ReSpeaker 2-Mic Hat not working - Unable to locate package and kernel version issues

Bump for this, I’m encountering the same thing, exact same output. Tried on both a RPi Zero W (v1.1) with 32-bit latest Raspbian fresh install, and RPi4 with 64-bit Raspbian frest install.

Also tried emailing them at [email protected], but haven’t gotten any reply yet.
