Homebrew install issue

[Billy-Night]

Hi, I am new here and new to the terminal. I have just tried to install Homebrew on my Mac Book Air m1 with Montery 12.1 and ran into some errors at the end of the install. Could someone please give me some advice as I am not massively confident with what I am doing in the terminal.
Here is the error code while Tapping homebrew/core
==> Tapping homebrew/core
remote: Enumerating objects: 1132093, done.
remote: Counting objects: 100% (100/100), done.
remote: Compressing objects: 100% (51/51), done.
error: RPC failed; curl 92 HTTP/2 stream 5 was not closed cleanly before end of the underlying stream

fetch-pack: unexpected disconnect while reading sideband packet
fatal: early EOF
fatal: fetch-pack: invalid index-pack output
Failed during: git fetch --force origin refs/heads/master:refs/remotes/origin/master

I also ran some quick checks after:
billy@billys-macbook-air ~ % command -v brew
billy@billys-macbook-air ~ % brew -v
zsh: command not found: brew
billy@billys-macbook-air ~ % brew --version
zsh: command not found: brew
billy@billys-macbook-air ~ % brew doctor
zsh: command not found: brew

So my current understanding is that it's not install (or not correctly) so would the best option be to try a reinstall or do I need to clear any data etc... Thanks

Did you follow the Next Steps shown to you by the installer? It should've looked something like

- Add Homebrew to your PATH in ~/.zprofile:
    echo 'eval $(/opt/homebrew/bin/brew shellenv)' >> ~/.zprofile
    eval $(/opt/homebrew/bin/brew shellenv)

You can do either.

I ran the uninstall, which was successful but when I restarted the terminal, I received the following:

/Users/billy/.zprofile:1: no such file or directory: /opt/homebrew/bin/brew
billy@billys-macbook-air ~ %

So, I opened the folder with the nano .zprofile and there is one line of code, which is :

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

Should I just delete this and start the re-install?

[carlocab]

You can keep it since you'll put it back anyway after reinstalling.

Just skip the next steps about adding brew to your PATH.

[Billy-Night]

Ok, all seems good.

But, I needed to add brew to my path again because there was no response from brew, so I just deleted the duplicated code after.

Everything looks good and it says ready to brew, so thanks for your help and patients.

It totally solves the problem!Thank you very much!

disabling HTTP/2 and using HTTP/1.1 fixes the sideband packet error:

run

git config --global http.version HTTP/1.1

then rerun the homebrew install script.
