Brewing up with Tekton

Having recently upgraded to macOS 12 Monterey, I also wanted to upgrade my Homebrew installation, which I did thusly: -

brew update

Updated 1 tap (homebrew/core).

No changes to formulae.

brew upgrade

Warning: Calling bottle :unneeded is deprecated! There is no replacement.

Please report this issue to the tektoncd/tools tap (not Homebrew/brew or Homebrew/core):

  /usr/local/Homebrew/Library/Taps/tektoncd/homebrew-tools/Formula/tektoncd-cli.rb:6

Reading this: -

Install tektoncd cli with brews

let me to this: -

brew untap tektoncd/tools

Warning: Calling bottle :unneeded is deprecated! There is no replacement.

Please report this issue to the tektoncd/tools tap (not Homebrew/brew or Homebrew/core):

  /usr/local/Homebrew/Library/Taps/tektoncd/homebrew-tools/Formula/tektoncd-cli.rb:6

Error: Refusing to untap tektoncd/tools because it contains the following installed formulae or casks:

tektoncd-cli

Given that I'm not currently using Tekton ( sad ), I took the "nuclear" option of removing tektoncd-cli 

brew remove tektoncd-cli
