Original GitHub issue: https://github.com/FiloSottile/mkcert/issues/519

Environment

  • Operating system (including version): Raspbian GNU/Linux 11 (bullseye) aarch64
  • mkcert version (from mkcert -version): zsh: exec format error: mkcert
  • Server (where the certificate is loaded): -
  • Client (e.g. browser, CLI tool, or script): Terminal / ZSH

What you did

I tried all install methods for linux but i couldnt get homebrew on my pi running and the same with go.

curl -JLO "https://dl.filippo.io/mkcert/latest?for=linux/amd64"
chmod +x mkcert-v*-linux-amd64
sudo cp mkcert-v*-linux-amd64 /usr/local/bin/mkcert

What went wrong

$ mkcert
$ zsh: exec format error: mkcert

Thats all the output.

@goldstar611 commented on GitHub (Apr 28, 2023):

Operating system (including version): Raspbian GNU/Linux 11 (bullseye) aarch64
and
chmod +x mkcert-v*-linux-amd64

That's a non-working combination there. You downloaded the amd64 binary and ran it on an aarch64 OS.

Get the linux-arm64 version ;)
