Cross compiling for ARM not working?

[filiberto7]

Hello,

I'm trying to cross compile to ARM and I'm getting the error below, looks like something to do with boringSSL? This is my command

cross build --target aarch64-unknown-linux-gnu

That's after running

rustup target add aarch64-unknown-linux-gnu

Am I doing something wrong?

Compiling statrs v0.16.1
