Facing issues while trying to cross compile to MacOs

[hbina]

I have no idea what I am doing. Does rust:latest use a trimmed version of Ubuntu or Alpine or something? Can't I just use ubuntu:latest and mimic a common Rustup installation setup instead?

The image is based off of Debian, not Ubuntu.

Yes, you can install Rust on to an ubuntu base image.

Do you have any idea how to fix this error?

I do not, but this repository is probably not the right place to ask for support on cross compiling from Linux to macOS.
