Bug report

• [ N/A ] ran brew update and can still reproduce the problem?
• [ N/A ] ran brew doctor, fixed all issues and can still reproduce the problem?
• [ N/A ] ran brew config and brew doctor and included their output with your issue?

What you were trying to do (and why)

I am trying to install Homebrew.

What happened (include command output)

I ran:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

Command output

Homebrew is not (yet) supported on ARM processors!

Rerun the Homebrew installer under Rosetta 2.

If you really know what you are doing and are prepared for a very broken experience you can use another installation option for installing on ARM:

https://docs.brew.sh/Installation
  

What you expected to happen

I expected it to install successfully, or give me more detailed instructions for this sentence: "Rerun the Homebrew installer under Rosetta 2."

Step-by-step reproduction instructions (by running brew commands)

1. Use a new MacBook with Apple Silicon M1 chip.
2. Try to install homebrew

Output of brew config and brew doctor commands

Trying to attempt the same

https://docs.brew.sh/Installation

cd /opt
mkdir homebrew && curl -L https://github.com/Homebrew/brew/tarball/master | tar xz --strip 1 -C homebrew
sudo chown -R $(whoami) /opt/homebrew

sudo nano /etc/path

Add this two paths

/opt/homebrew/bin
/opt/homebrew/opt

Restarting terminal and brew update

I don't know if this is the right solution but it is working fine. I just have issues with specific formulas like "gpg"

There’s a PR in progress to explain exactly that in more detail.

From the PR (referring to installing a formula):

To use it, you can choose between:

• running your Terminal from Rosetta 2
• running arch -x86_64 brew instead of brew.

To install Homebrew itself, you can run arch -x86_64 /bin/bash instead of /bin/bash.
To configure Terminal to run under Rosetta 2, select Terminal.app in Finder, hit ⌘I, select Open with Rosetta, then restart your Terminal.

@medweb2020 If you need support, please go to our Discourse and ask your questions there: https://discourse.brew.sh

I feel your pain. But GitHub issues are a space for reporting bugs and proposing features, and we absolutely need it to stay that way so we have a chance to do our work properly. I must insist that you please stop asking for support on GitHub issues.
