It looks like the official Parrot OS Raspberry Pi builder is located on GitHub?
And the image builder is here
I noticed it would try to build Parrot 3.5 (very old build) if I had the proper signing key. Should I bother tinkering with anything or just leave this alone until a competent developer has time to work on it? I’m willing to assist in testing (on a 3B+), but I imagine any possible future focus would mainly be on the Raspberry Pi 4. My apologies for creating a Raspberry Pi post, when there are others. I tried the latest headless image for Raspberry Pi, but am having lack of knowledge issues setting up wireless from the command line. LOL
