Invalid formula on M1 mac

[lazjake]

Ran into this error trying to brew install instrumenta on an Apple 2021 M1 Pro Monterey -- any idea how to resolve?

I have the same problem on Ubuntu 20.04.

@lazjake kubeval is currently unmaintained. A couple options:

1. I created my own tap for the last maintained version of kubeval (v0.16.1). It works on my M1/M2 macs.

brew tap dcchambers/tap
brew install dcchambers/tap/kubeval

2. kubeconform is a modern, maintained replacement that you may want to consider instead.
