Linux Brew Installation Error?

Habe Linux Ubuntu auf meinem MacOS

Ich versuche im Terminal mit folgendem Command Brew zu installieren:

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

bekomme folgende Fehlermeldung:

Do not file an issue on GitHub about this; you will need to figure out for

yourself what issue with your internet connection restricts your access to

GitHub (used for Homebrew updates and binary packages).

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
