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

[istvan60]

Hi Everyone,

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!

I'd try something like curl -LSvI https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh to help diagnose what curl is doing, if there's no errors then remove the capital I from the params and see if you get the file. When I run that I see it ends up using TLSv1.2, I'm also on a 11.1 (M1) and installed brew a couple weeks ago using the default command. If for whatever reason curl is stuck on TLSv1 you can try forcing --tlsv1.2.

Worst case, or maybe easiest case, use your browser to just download https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh and run it manually

Thanks for the comment, I did give it a try, but I do not notice any difference....any ideas?

Sorry, forgot to "pin" the curl invocation:

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)"

gromit! That seems to have done the trick!!! except for one error! You're awesome,

HEAD is now at 111777ccf1 pandoc: update 2.11.4 bottle.

You can ignore this...

**Warning: /opt/homebrew/bin is not in your PATH.**

...but not this...

==> Next steps:
- Add Homebrew to your PATH in /Users/hatvaniistvan/.profile:
    echo 'eval $(/opt/homebrew/bin/brew shellenv)' >> /Users/hatvaniistvan/.profile
    eval $(/opt/homebrew/bin/brew shellenv)

Failure to do the above is a very common reason for "I just installed Homebrew with no errors! Why can't I use it?"

[istvan60]

Done, and I updated it as well!

Thanks everyone!!!! 🙏
