Warning: A newer Command Line Tools release is available.
Update them from Software Update in System Preferences or run:
  softwareupdate --all --install --force

If that doesn't show you an update run:
  sudo rm -rf /Library/Developer/CommandLineTools
  sudo xcode-select --install

Alternatively, manually download them from:

Warning: You have unlinked kegs in your Cellar.
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run `brew link` on these:

Warning: You are using macOS 11.0.
We do not provide support for this released but not yet supported version.
You will encounter build failures with some formulae.
Please create pull requests instead of asking for help on Homebrew's GitHub,

Warning: Homebrew's sbin was not found in your PATH but you have installed

Consider setting the PATH for example like so:
