Brew installation fails due to Ruby versioning?

I am trying to install [Linux Brew](https://brew.sh) on [Garuda Linux](https://garudalinux.org) (Arch Linux based distro) but the install script fails with the following error: ==> Pouring portable-ruby-2.6.8.x86_64_linux.bottle.tar.gz Error: Failed to install ruby 2.6.8! Error: Failed to install Homebrew Portable Ruby and cannot find another Ruby 2.6.8! If there's no Homebrew Portable Ruby available for your processor: - install Ruby 2.6.8 with your system package manager (or rbenv/ruby-build) - make it first in your PATH - try again Failed during: /home/linuxbrew/.linuxbrew/bin/brew update --force --quiet I verified that Ruby exists on the system: ➜ ruby --version ruby 3.0.3p157 (2021-11-24 revision 3fb7d2cadc) [x86_64-linux] Is it complaining that Brew wants a particular version? I found [one](https://arstechnica.com/civis/viewtopic.php?f=16&t=1482948) or [two](https://www.reddit.com/r/ManjaroLinux/comments/t9zs67/homebrew_help_on_new_manjaro_install/) other users who posted the same error in recent days. The latter is also an Arch-based system and got the suggestion to install pkgconf, which I verified is installed on my system. ➜ pkgconf --version 1.8.0 I can't seem to figure out what the problem is ... any suggestions? I am new to Arch Linux based distributions.
