./build-docker.sh error "setarch: failed to set personality to linux32: Invalid argument"

[naturaverl]

Hi, first time pi-gen user here. I'm on a M1 mac, trying to use pi-gen to build a standard image (nothing's been added in by me, yet)

I'm trying to follow the README to learn how to use pi-gen, and understand that I can use Docker for pi-gen to have a debian environment to run from. On my Mac mini M1 system, I've simply cloned from pi-gen master branch, am using the build-docker.sh script, and the simplest of uses is failing for me. [EDIT] I've checked out the arm64 branch and that works better for me. The README didn't specifically mention needing to run the arm64 branch if your host is arm64.

Sorry it didn't all go as smoothly as it should've. I'm not familiar with Macs at all, so I'm not sure I'll be of much help here.

Do you need to build armhf images or arm64 images? If you don't need armhf images, you could try building from the 'arm64' branch and see if you have better luck.

Otherwise, do M1 macs support arm32 instructions natively or only aarch64? If it's only aarch64, then there's not much of a chance that this will work.
