Trying to clean reinstall on Big Sur

[kelleydac]

I had homebrew working on Catalina and recently upgraded to Big Sur. I tried to remove and reinstall home-brew from scratch using the installer script, as shown below, but cannot get past the "Bad file descriptor" error:
~ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
==> This script will install:
/usr/local/bin/brew
/usr/local/share/doc/homebrew
/usr/local/share/man/man1/brew.1
/usr/local/share/zsh/site-functions/_brew
/usr/local/etc/bash_completion.d/brew
/usr/local/Homebrew

Press RETURN to continue or any other key to abort

I think there's a problem with your connection. See #190 (comment)
