Homebrew Installation Issue

Fairly new at Linux here and have a question about installing Homebrew. I'm using Centos7 and already updated all the required dependencies (cURL, etc.). When I run the Linux installation script from the Homebrew homepage, the process fails with the following error:

==> /usr/bin/sudo /bin/chown -R username:username /home/linuxbrew/.linuxbrew/Homebrew
==> Downloading and installing Homebrew...
remote: Enumerating objects: 16, done.

Has anyone seen this before, or might be able to point me in the right direction? I couldn't find any info pertaining to this particular installation failure anywhere else the I looked during my research. Per comment, adding lines from

/home/linuxbrew/.linuxbrew/bin/brew

:

#!/bin/bash    #line 1
#lines 21-28:
# Fail fast with concise message when requesting unfiltered environment.
# This is basically odisabled so can be removed at any major release afterwards
# and definitely if this is still here in 2023.
if [ -n "${HOMEBREW_NO_ENV_FILTERING}" ]
then
  echo "Error: HOMEBREW_NO_ENV_FILTERING was deprecated for over a year and has now been removed (because it breaks many things)!" >&2
  exit 1
fi

Edit: Here is the exact install command I ran, from the Homebrew homepage:

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

Thanks!
