Homebrew won't install on Big Sur (OS X 11.1) (M1)

Question

I'm trying to install Homebrew on my OSx 11.1

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

But I get the following error:

curl: (35) error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version /bin/bash: not found

I found similar errors reported when trying to install Homebrew on old OSX systems, but this is not the case here. Does anyone have any idea what should I do?

Thank you!

Answer 1

I was not using the system tools here. which curl returned:

/opt/local/bin/curl

So I tried reducing the installer's PATH to the basics with the code below:

PATH="/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin /bin/bash -c "$(/usr/bin/curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Than added Homebrew to my PATH in /Users/hatvaniistvan/.profile with

echo 'eval $(/opt/homebrew/bin/brew shellenv)' >> Users/hatvaniistvan/.profile

eval $(/opt/homebrew/bin/brew shellenv)

This solved the problem and I managed not just install, but update homebrew as well.

maybe your curl is somehow linked to an older version(like macports). check the curl path and make sure you are using /usr/bin/curl.
