Hi, I’ve tried installing the libraries on my Zymkey 4i many times, but none of the attempts were successful. I have a product built on the Raspberry Pi 4B, and the last thing was to secure the data. After I got the Zymkey, I followed every single step from the https://docs.zymbit.com/getting-started/zymkey4/quickstart/ tutorial, and everything seemed to look normal on my 64-bit Raspberry Pi OS Bullseye (Raspbian OS GNU/Linux 11) with Python 3.9.2 as the default Python version, but when I tried importing the zymkey library, I got an ImportError: No module named zymkey. I searched the internet for a solution and found: ImportError: No module named zymkey but with no result because running the installing command twice had no effect, and @alohaJoe solved the problem by installing a clean installation of 64-bit Bullseye. But when I tried a clean installation of 64-bit Bullseye, 32-bit Bullseye, or 64-bit Bookworm with the default Python version of 3.11.2 or 3.9.2, the best I could get was:
E: Failed to fetch https://zk-sw-repo.s3.amazonaws.com/apt-repo-bookworm-aarch64/dists/bookworm/InRelease 403 Forbidden [IP: ...]

This error showed up on my Bullseye and Bookworm versions.
