This is a super-long shot, but:
Have anyone managed to install Rosetta-compatible #Homebrew on #MacOS #Sonomoa? (Boost appreciated!)

What I’m trying to do, BTW., is making a #QMK build environment (https://docs.qmk.fm/#/newbs_getting_started)- I’m using this guide for Homebrew: https://stackoverflow.com/questions/64882584/how-to-run-the-homebrew-installer-under-rosetta-2-on-m1-macbook

First I got asked to update my command line. That doesn’t work the normal way - but installing the beta manually works fine, However, when I try to install Homebrew (Rosetta), it asks for the normal update again. 😕
